Yosemite and Mail massive memory leak and excessive CPU usage

I've just installed Yosemite and upgraded to 10.10.2 via the AppStore. Now I have a problem with Mail sucking up all the CPU (>106% !) and memory (>8Gb and rising while doing nothing). Everything runs fine when I quit Mail. Very disturbing behaviour!
I've tried several suggestions found elsewhere on the board here, such as turning off and even removing all Mail plug-ins including SpamSieve, but without positive results. I've tried un-selecting 'Store draft msgs on server', as well as the option for junk and sent msgs. but again without any difference. Going Offline within Mail also makes no difference to its memory hogging or CPU usage.
I notice this is an issue that's been around since last year (wish I'd known that before upgrading to Yosemite today) and I am just completely flabbergasted that it still exists. Would've thought Apple'd have fixed it in the first but certainly in the second incremental OSX Yosemite release.
Is there anything else I could try that's proven to be effective in stopping Mail's massive memory leak?

Okay, I've run Disk Util and restarted. Seems to have made a little bit of a difference to the RAM gobbling in that it appears to be going at a slower rate, but it's still up at around the 45Gb after an hour. Here's the EtreCheck report in the hope that it helps.

  • IDCS5 Mac - Massive memory leaks - Followup to previous discussion

    Hello Everyone:
       After some painful, tedious marching though the code on the Mac, I found something really, really strange.  The code seemed to be working fine, except when a couple of documents were added in the scan jobs.  I isolated one of the documents and removed each object on the page until I came across the object that, when scanned, caused InDesign to report the massive memory leaks.
       The object was a quarter-inch by quarter-inch overset text frame (that's .63 cm by .63 cm for those of you who are used to the more sensible metric system).  In the text frame was a single character, not normally visible when on the page.  According to the ASSERT dialog box that was thrown up on the screen when InDesign was shutting down, this little bitty object was the source of 104450 leaks amounting to between 38,000,000 abd 51,000,000 bytes in leaks.  Here's the code where the leaks must be coming from (and Dirk, I owe you a crow pie...as in I'm gonna have to eat crow...I use PMString for one small command in this snippet, but it seemed so much faster and simpler than what the examples in widestring.h were suggesting):
    //  TI is TextIndex, assigned from a call to IMultiColumnTextFrame::TextStart()
    //  TS is int32 assigned from a call to IMultiColumnTextFrame::TextSpan()
    WideString Text;
    TextIterator beginTextChunk(FrameTextModel,          TI );
    TextIterator endTextChunk(   FrameTextModel, (TS + TI));
    std::copy(beginTextChunk, endTextChunk, std::back_inserter(Text));
    PMString PMText(Text);
    std::string text = PMText.GetPlatformString();
    IdentifyNamesInText(text);
    This final function call could not have been the source of the problem because one of the steps I took in tracking down the problem was to put "return" as the first line in its implementation but the bug still occurred.

    Hi, I don't know if this is relevant or not, particularly since we're on Windows and the problem you're seeing is on Mac.
    One of our guys put in some code to workaround a problem which he encountered using std:;copy with TextIterators under VS2005 (so it would have been CS4)
    /// Alternative to using std::copy to workaround issues using std::copy and TextIterator's in VS2005
    inline void TextIteratorCopy( TextIterator& posBegin, TextIterator& posEnd, WideString& strDest )
        std::back_insert_iterator < WideString > posDest = std::back_inserter( strDest );
        for ( ; posBegin != posEnd; ++posDest, ++posBegin )
            *posDest = *posBegin;
    that said, it might not affect you on the Mac, it might no longer be an issue with CS5 either.

  • I have just updated OX10.8.5 and mail has gone mad and ^have lost emails

    I have just updated my I mac (OSX 10.8.5) and mail has gone mad and I have lost a lot of emails additionally it keeps requesting me to enter my email password..

  • Mountain Lion Mail excessive CPU usage

    Evers since upgrading to ML 10.8 and 10.8.1, Mail heats the CPU up to 100% after a couple of minutes and remains like this forever. Absolutely reproducible. Mail is unusable for me.
    I have some 25.000 Mails in my Inbox. Sampling Mail  always reveals the same pattern. Looks like Mail is constantly iterating over my 25.000 emails and tries to layout them. Looks crazy to me.
    Here is an excerpt of the sample:

    This problem was solved.
    After a lot of frustration (restoring Lion backup and performing the update several times), I managed to have a stable installation without the problem of high CPU usage and high temperatures.
    It seems that the installation procedure has an issue, when your user directories are located in an external disk. In this particular case, after the installation of the server software, the two links in /Network/Servers directory, pointing to the / directory, do not get created, so you need to do that manually.
    That, in itself, was not causing my excessive CPU usage, but it didn't allow my users to log in the server. Thinking that this was the issue described in http://support.apple.com/kb/TS2938, I was running the command described in the previous link to fix the issue. That command (sso_util configure -r REALM_NAME -a diradmin afp) was what was killing my CPU.
    All is well, when it ends well, I guess.

  • I have iTunes 10.4 and every time I open it my CPU usage hits 100%.  How do I stop this?

    I have iTunes 10.4 and every time I open it my CPU usage hits 100%.  This makes my computer really slow and almost unusable.  How do I stop this?  Another effect is that I cannot log onto the iTunes Store.  I click on it and it says it is loading the iTunes store but the window remains blank.

    So do I!

  • 10.9.4 excessive CPU usage

    And now a strange case...
    Installed 10.9.4 but it became unusable because of excessive CPU usage. Reverted back to 10.9.3 but now the problem persists!
    Basically, if connect the Ethernet cable the CPU increases and temp raises from 45C to 95C. As soon as I remove the Ethernet cable and stay on WiFi things go back to normal. I already have done the most obvious, i.e. reinstalling the OS from time machine, removing launch daemons and plug-ins, and fixing disk permissions. Check the details below. Any idea? It would be much appreciated. I'm getting nuts with this.

    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • Launching Mail becomes a runaway process and creates a massive memory leak in the kernel task

    I have 16gig of ram, my kernel task is currently using 12gig, Mail is no longer responding while using all remaining ram
    Mail has been jammed at 100% of one i7 core for about 2 hours now, disk activity is almost nonexistant.
    it was running poorly yesterday, rebuilding the mailboxes did not yeild a positive effect
    permissions and drive check out
    Quicklook is also reporting a lot of bs when finder windows are open:
    example:

    I feel your pain!
    Mac Pro with 32 GB, and Mail takes about 5 minutes to "start" - well, show the Mail Menu. Then, another few minutes to actually draw the window... but wait, it STILL needs more time to actually show the accounts and mail.
    The (stupid) new Activity Monitor show Mail using 12 GB of RAM, and several com plist files also sucking up CPU time and RAM. Why Apple has to dumb-down good information to "Memory Pressure" is beyond me!
    I have reported thsi to Apple, and they had a Support person get in touch with me. I have sent several spindumps and tarball files last week, but no reply. Today, I pinged the support person who said Apple Engineering was reviewing the information, and would likely get back sometime as *maybe* some others were experiencing this problem...

  • Yosemite - Mail.app memory leak

    I'm seeing a recurring issue with Mail.app taking up huge amounts of RAM memory.  There's evidently a serious memory leak in Yosemite Mail.  On three occasions today, I noticed my free memory below 20 MB (I have 16GB).  Activity Monitor shows the culprit to be Mail.app taking any where from 20-65GB of memory!  I've had to quit Mail and restart it, only to have the same issue surface later.  Does anyone have a way to mitigate/resolve this issue?

    I apologize this is not the Discussion that has all the solutions. It's this one:
    Yosemite OS 10.10 Mail Memory Leak
    There are 19 pages so far, I'll see if I can find my post with the suggestions. Found it, it was on page 7. Here ya go. Hope it works!

    Re: Yosemite OS 10.10 Mail Memory Leak
    in response to Doug Lerner2
    Thanks mlwebber & etresoft. I think we were able to narrow down the 4 most effective methods of temporarily resolving this issue it seems. I only had to disable the drafts to get back to normal, but others are reporting that using that in conjunction with a combination of 3 of the other methods from mlwebber are resolving their issues. Albeit this is only a temp fix until Apple updates their software & truly fixes this bug/issue, but, at least, I hope, we all can get back to business as normal for the time being.
    Doren (from etresoft’s observations):
    - Preferences/Accounts/Mailbox Behaviors: UNCHECK “Store draft messages on the server”
    mlwebber:
    - Preferences/Accounts/Advanced: UNCHECK “Use IDLE command if the server supports it”
    - Preferences/General/Check for new messages: “Every 5 minutes”
    - Preferences/Junk Mail: UNCHECK “Enable junk mail filtering”
    Please post in this discussion if none of these methods help you and we'll see what we can do. We'd also love to know if these methods also resolve your issue. Thank you.

  • Firefox has a memory leak and I need to update it, but I want to keep 3.5 because I don't like how the newest version of Firefox is set up.

    My computer is running low on RAM, and when I look at what processes are using the most memory, firefox is the number one using between 28,000 to 93,000k, so I'm guessing that it has a memory leak.
    And because of that memory leak I have to update firefox, however I really dislike the newest version of firefox and I'd prefer to stick with the version I have, which is 3.5.

    Often the memory problems are not just from Firefox in isolation, but partly relating to all the extensions available for it and then the videos and animations it runs on media rich sites.
    The first thing to do is to upgrade to firefox 3.6 which is at least a supported version (Maybe not for much longer)
    * see [[updating firefox]]
    Next version after 3.6 is 4, you should avoid that, it did have some memory problems, that were worse than 3,6 and firefox 4 is no longer secure or supported.
    The techies at Firefox have been working on memory problems recently and have made many improvements, but some of these improvements are only seen in the trial versions of Firefox.
    I would in fact suggest you upgrade to Firefox 5 the current release version (soon to be replaced with Firefox 6)
    I am able to run Firefox v3.6 to v8 on legacy XPs with less than 1GB RAM. Firefox in itself is not necessarily very demanding in terms of RAM. I am not sure what the figures are you are quoting, or whether they are high. ( Note 1Gb is in the order of 1 000 000 k )
    As for not liking the set-up of new versions of Firefox, there is quite abit that can be changed, maybe you would be able to configure it more to your liking with little effort.

  • Memory leak and char[] ?

    Hello all,
    I'm not sure whether this post should be here or in WebLogic section, so correct me if I'm wrong.
    I'm working on JDeveloper 11.1.1.3 while deployments are made on standalone WebLogic 10.3.3. This thing occurred in previous versions also.
    With every deployment WebLogic increases it's used memory until the famous PermGen space error, which is after about 5-6 deployments.
    I'm doing my best to understand how to use memleak detection tools. I've switched JDev and WL from Sun jdk which was used before to JRockit, same thing happens. Both JDev's memory profiler and JRockit mission control show something that I really do not understand. char[] uses around 30% of heap space and keeps growing with deployments, next is String with 8%. I never use char in app.
    Am I looking at the wrong thing? Is it normal for char[] to increase on WebLogic on deployments? Does anyone know how to check other things and what to check? Someone on other forums mentioned it would be useful to check if ApplicationContext keeps initializing over again on deployments. Does anyone know how to check this?
    One more thing, I have successfully deployed app on Tomcat, and Tomcat said there is a memory leak in app, but could not tell anything specific.
    I'm kinda lost in this :(

    It is normal for the PermGen space of the Sun's JVM to get filled after several re-deployments. PermGen stands for "permanent generational". This space is used by classes that is unlikely to need to be garbage-collected, so they are placed in this memory space that is never garbage-collected (for example, the Class instances). When you redeploy an application, a new class loader instance is used and it instantiates new Class instances that fill up the PermGen space. But why this happens on JRockit either, I could not explain.
    We have experienced memory leaks related to classes and components that use native memory. For example, we have had significant memory leak when using Oracle's JDBC OCI driver. We were not able to solve this problem, so we switched to JDBC Thin driver (which is very performant and stable today comparing to some years ago). If you are using Oracle JRockit, you can monitor the overall memory usage by the following JRockit command executed at OS command line:
    jrcmd <jrockit_pid> print_memusage>where <jrockit_pid> should be replaced by the JVM process ID.
    If you suspect existence of native memory leaks, then have a look at the article Thanks for the memory for explanations about how Java uses native memory.

  • I think I've got a memory leak and could use some advice

    We've got ourselves a sick server/application and I'd like to gather a little community advice if I may. I believe the evidence supports a memory leak in my application somewhere and would love to hear a second opinion and/or suggestions.
    The issue has been that used memory (as seen by FusionReactor) will climb up to about 90%+ and then the service will start to queue requests and eventually stop processing them all together. A service restart will bring everything back up again and it could run for 2 days or 2 hours before the issue repeats itself. Due to the inconsistant up time, I can't be sure that it's not some trouble bit of code that runs only occasionally or if it's something that's a core part of the application. My current plan is to review the heap graph on the "sick" server and look for sudden jumps in memory usage then review the IIS logs for requests at those times to try and establish a pattern. If anyone has some better suggestions though, I'm all ears! The following are some facts about this situation that may be usefull.
    The "sick" server:
    - CF 9.0.1.274733 Standard
    - FusionReactor 4.0.9
    - Win2k8 Web R2 (IIS7.5)
    - Dual Xeon 2.8GHz CPUs
    - 4GB RAM
    JVM Config (same on "sick" and "good" servers):
    - Initial and Max heap: 1536
    -server -Xss10m -Dsun.io.useCanonCaches=false -XX:PermSize=192m  -XX:MaxPermSize=256m -XX:+UseParNewGC -Xincgc -Xbatch -Dcoldfusion.rootDir={application.home}/../ -Dcoldfusion.libPath={application.home}/../lib -Dcoldfusion.dotnet.disableautoconversion=true
    What I believe a "healthy" server graph should look like (from "good" server):
    And the "sick" server graph looks like this:

    @AmericanWebDesign, I would concur with BKBK (in his subsequent reply) that a more reasonable explanation for what you’re seeing (in the growth of heap) is something using and holding memory, which is not unusual for the shared variables scopes: session, application, and/or server. And the most common is sessions.
    If that’s enough to get you going, great. But I suspect most people need a little more info. If this matter were easy and straightforward, it could be solved in a tweet, but it’s not, so it can’t.
    Following are some more thoughts, addressing some of your concerns and hopefully pointing you in some new directions to find resolution. (I help people do it all the time, so the good news is that it can be done, and answers are out there for you.)
    Tracking Session Counts
    First, as for the observation we’re making about the potential impact of sessions, you may be inclined to say “but I don’t put that much in the session scope”. The real question to start with, though, is “how many sessions do you have”, especially when memory use is high like that (which may be different than how many you have right now). I’ve helped many people solve such problems when we found they had tens or hundreds of thousands of sessions.  How can you tell?
    a) Well, if you were on CF Enterprise, you could look at the Server Monitor. But since you’re not, you have a couple of choices.
    b) First, any CF shop could use a free tool called ServerStats, from Mark Lynch, which uses the undocumented servicefactory objects in CF to report a count of sessions, overall and per application, within an instance. Get it here: http://www.learnosity.com/techblog/index.cfm/2006/11/9/Hacking-CFMX--pulling-it-all-togeth er-serverStats . You just drop the files (within the zip) into a web-accessible directory and run the one CFM page to get the answer instantly.
    c) Since you mention using FusionReactor 4.0.9, here’s another option: those using FR 4 (or 4.5, a free update for you since you’re on FR 4) can use its available (but separately installed) FusionReactor Extensions for CF, a free plugin (for FR, at http://www.fusion-reactor.com/fr/plugins/frec.cfm). It causes FR to grab that session count (among many other really useful things about CF) to log it every 5 seconds, which can be amazingly helpful. And yes, FREC can grab that info whether one is on CF Standard or Enterprise.
    And let’s say you find you do have tens of thousands of sessions (or more). You may wonder, “how does that happen?“ The most common explanation is spiders and bots hitting your site (from legit or unexpected search engines and others). Some of these visit your site perhaps daily to gather up the content of all the pages of your site, crawling through every page. Each such page hit will create a new session. For more on why and how (and some mitigation), see:
    http://www.carehart.org/blog/client/index.cfm/2006/10/4/bots_and_spiders_and_poor_CF_perfo rmance
    About “high memory”
    All that said, I’d not necessarily conclude so readily that your “bad” memory graph is “bad”. It could just be “different”.
    Indeed, you say you plan to “look for sudden jumps in memory usage“, but if you look at your “bad” graph, it simply builds very slowly. I’d think this supports the notion that BKBK and I are asserting: that this is not some one request that “goes crazy” and uses lots of memory, but instead is the “death by a thousand cuts” as memory use builds slowly.  Even then, I’d not jump at a concern that “memory was high”.
    What really matters, when memory is “high” is whether you (or the JVM) can do a GC (garbage collection) to recover some (or perhaps much) of that “high, used memory”. Because it’s possible that while it “was” in use in the past (as the graph shows), it might no longer be “in use” at the moment . 
    Since you have FR, you can use its “System Metrics page” to do a GC, using the trash can in the top left corner of the top right-most memory graph. (Those with the CFSM can do a GC on its “Memory Usage Summary” page, and SeeFusion users can do it on its front page.)
    If you do a GC, and memory drops q lot, then you had memory that “had been” but no longer ”still was” in use, and so the high memory shown was not a problem. And the JVM can sometimes be lazy (because it’s busy) about getting to doing a GC, so this is not that unusual. (That said, I see you have added the Xincgc arg to your JVM. Do you realize that tells the JVM not to do incremental GCs? Do you really want that? I understand that people trade jvm args like baseball cards, trying to solve problems for each other, but I’d argue that’s not the place to start. In fact, rarely do I find myself that any new JVM args are needed to solve most problems.)
    (Speaking of which, why did you set the – xss value? And do you know if you were raising or lowering it form the default?)
    Are you really getting “outofmemory” errors?
    But certainly, if you do hit a problem where (as you say) you find requests hanging, etc., then you will want to get to the bottom of that. And if indeed you are getting “outofmemory” problems, you need to solve those. To confirm if that’s the case, you’ll really want to look at the CF logs (specifically the console or “out” logs). For more on finding those logs, as well as a general discussion of memory issues  (understanding/resolving them), see:
    http://www.carehart.org/blog/client/index.cfm/2010/11/3/when_memory_problems_arent_what_th ey_seem_part_1
    This is the first of a planned series of blog entries (which I’ve not yet finished) on memory issues which you may find additionally helpful.
    But I’ll note that you could have other explanations for “hanging requests” which may not necessarily be related to memory.
    Are you really getting “queued” requests?
    You also say that “the service will start to queue requests and eventually stop processing them all together”. I’m curious: do you really mean “queuing”, in the sense of watching something in CF that tells you that? You can find a count of queued requests, with tools like CFSTAT, jrun metrics, the CF Server Monitor, or again FREC. Are you seeing one of those? Or do you just mean that you find that requests no longer run?
    I address matters related to requests hanging and some ways to address them in another entries:
    http://www.carehart.org/blog/client/index.cfm/2010/10/15/Lies_damned_lies_and_CF_timeouts
    http://www.carehart.org/blog/client/index.cfm/2009/6/24/easier_thread_dumps
    Other server differences
    You presented us a discussion of two servers, but you’ve left us in the dark on potential differences between them. First, you showed the specs for the “sick” server, but not the “good” one. Should we assume perhaps you mean that they are identical, like you said the JVM.config is?
    Also, is there any difference in the pattern of traffic (and/or the sites themselves) on the two servers? If they differ, then that could be where the explanation lies. Perhaps the sites on one are more inclined to be visited often by search engine spiders and bots (if they sites are more popular or just have become well known to search engines). There are still other potential differences that could explain things, but these are all enough to hopefully get you started.
    I do hope that this is helpful. I know it’s a lot to take in. Again, if it was easier to understand and explain, there wouldn’t be so much confusion. I do realize that many don’t like to read long emails (let alone write them), which only exacerbates the problem. Since all I do each day is help people resolve such problems (as an independent consultant, more at carehart.org/consulting), I like to share this info when I can (and when I have time to elaborate like this), especially when I think it may help someone facing these (very common) challenges.
    Let us know if it helps or raises more questions. :-)

  • Flash player 11.6 r602 memory leak and crash in FF 19.0

    I have seen similar questions like this but have never witnessed it myself until today when Flash updated on FF 19.0. I'd like to see if this is Firefox or Adobe as the later is quick to say "this is normal".
    I watch two streams (uStream and live.twit.tv) almost all the time that use flash on both sites. Usually it caps out at around 250MB and worked just fine this morning on uStream and is stable. Just got the Flash 11.6 update and neither currently work and will lock-up Firefox and eventually crash Adobe, which then frees up Firefox to allow me to use it again. It slowly creeps up to 1.9G before Adobe crashes.
    I have tried, as suggested elsewhere on a very similar issue, to roll back to Adobe 10, add "ProtectedMode = 0" to the mms.cfg file in the macromed folders, and disabling hardware acceleration in Firefox options. This allowed Firefox to play flash media, but only after it as reached 2.8G of memory on an 8G physical memory machine (Adobe claims 10% is normal, which this is far beyond 10% of 8G)
    I'd be quicker to blame Adobe on this, but I just got Firefox 19 the past 7 days, Adobe had always worked on Firefox before this update, but now even rolling back doesn't seem to work well at all. I'm not sure how to post my reports from about:crashes here, but...
    bp-492ad7e0-2bf8-46cb-b558-596252130228 2/27/20134:01 PM
    ...is my latest (Eleven reports today). I have screenshots of both Adobe v10 and v11 leaking memory, but don't feel it's useful at this time.
    Any help would be awesome and if it's not Firefox at all I guess I'll head back to Adobe with some more meat and potatoes for a more thorough support ticket over there. I just don't like having to use Chrome since it seems to work just fine on these pages ;)

    Thanks for your prompt and helpful reply.....
    When dealing with such a large problem with frequent FF lockups the temptation is to lump all information in an attempt to solve. LOL
    Chasing multiple threads to help solve the problem may be helpful to the developers but it takes far too much time following and posting in each thread. As you can see it's taken a couple of days to get back to this post.
    First thing we did is dump cache and cookies both through the interface and then manually in the profile. We changed the version of Flash installed manually and even changed the version of FF. There are many "flash" enabled pages we encountered which caused the lockup.....so MSN is not specifically the issue.
    But when Flash is removed or disabled the browser no longer locks up.....suffice to say we get an error when visiting a website with flash content on it.
    That is why I chose to post here as the problem is directly attributable to Flash in FF on all of our machines.

  • Memory leaks and multi threading issues in managed client.

    In our company we use a lot of Oracle, and after the release of the managed provider we migrated all applications to it. First the  things were very impressive : the new client was faster, but after some days applications that uses 100MB with old client goes to 1GB and up. The memory is not the only issue, we use a lot of multi threading, and we experience connection drops and not disposal, after 1 days working one of the application had over 100 sessions on the server. I think there is something wrong with connection pool and multi threading.
    Is someone experience same problems.
    Yesterday we went back with unmanaged provider. Now things are back to normal.

    connection drops: did you try to use "Validate Connection=true" parameter in your connection string?
    the new client was faster: are you sure with this statement? Even in 64bit environment? I got quite serious performance problems when running application under 64bit process: https://forums.oracle.com/thread/2595323

  • Memory Leak and 100% CPU in slapd process when using Open Directory OS X 10.8.5

    Has anyone seen the slapd (LDAP daemon from OpenLDAP which OS X Server uses) run away when running Open Directory? We've tried disabling replication but it doesn't seem to matter. The slapd process will start up and take up about 400MB and then at night will consume all the available memory and crashing the server.
    Any thoughts? Any benefit in upgrading to Mavericks' Server app?
    Thanks,
    John

  • Why don't you get some c/c++ grizzled veterans on your team and fix the memory leaks that have dogged FireFox ever since the beginning?

    It's not plugins or extensions. This is a problem that never goes away. Memory usage creeps up into the multiple GBs (I have 12 GB of ram, the more you give the more it takes), and eventually the little OOPS Firefox crashed dialog is the only thing running. What about reviving the Electrolysis project for multi-process operation? In modern versions of IE and Chrome, this capability is so useful to kill off offending tabs.

    Electrolysis is alive and well, and is currently hot on track for a future release. Please note that Electrolysis (or per-tab process) doesn't improve memory usage (In fact Chrome has significantly worse memory usage than Firefox because of it). One thing we are trying to do right is make sure we don't worsen memory usage because of Electrolysis.
    Memory usage is something that's difficult to work on with little information, so if you want help please provide us some more data such as your about:support (type it in your url bar and press enter) and your about:memory (same)
