How to diagnose
Hi,
i am new and want to know how to diagnoes the DB.
Thanx in advance
Navneet Kaur
Navneet,
Hope you won't give one answer by post... there should some hundreds to give you advices.
Please explain a little bit more what you want to achieve.
Have you read the doc link provided by Rob ealier ?
Have you check any documentation about statspack ?
Generally, tunning is not the first step of Oracle Database knowledge.Some others knowledge are required (like the Concepts...).
And to start, what did you mean by diagnose ? Then what did you mean by "why performence is week" ? Have you receive users complaints ?
Please, for more understanding, give us more and more information.
Nicolas.

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this?
First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful. -
How to diagnose dead battery vs. something more serious?
I'm in the 11th month of ownership of an MBA, purchased brand new last year. 128MB model.
My battery, I believe, is dead but I'm not sure how to diagnose the matter.
Here's what's lead me to this conclusion:
MBA charger light stays off when plugged in (not dim, but off). I've had the dim light issue as well, earlier this year, and Apple replaced the charger. This time, however, the light stays completely off.
Battery icon in top right corner tells me that no charger is plugged in. The icon is in battery mode.
Battery charge keeps decreasing steadily in % value despite charger being plugged in, indicating that battery is continually discharging.
My wife has an MBP, and I've used her 85W charger on my MBA with the same result... i.e charger light stays off. I know that the MBP charger is in good health as it charges the MBP with no issues (orange light).
I've used my MBA charger on her MBP, and it charges the MBP just fine!!! (orange light)
I've done an SMC and NVRAM reset on the MBA, which hasn't affected the situation.
Since I'm on 15% charge on the MBA, I've shut it down and have booked an appointment with Apple to have it looked at.
In the mean-time, I'm hoping to get some clues from fellow MacBook users on this forum.
I've read somewhere that if it is indeed the battery that's faulty, then once the charger is unplugged, the MBA should turn off immediately. This isn't the case for me... I'm able to run off battery (whatever tiny amount of charge I have left) with the charger unplugged.
Hence, I've ruled out the charger being faulty. I'm not so sure that the battery is faulty. I'm thinking the issue might lie elsewhere... maybe the magsafe connector on the MBA?
I should also mention that when I opened the lid on the MBA earlier this evening, before noticing this charging issue, the screen flickered brightly once. The screen looked and operated normally after the flicker. Not sure if there's a connection. I'm beginning to think there is.
I should also add that, even though the MBA has been a pleasure to use, the past 11 months haven't been trouble-free... which adds to the suspicion that the issue might indeed be somewhere deeper.
A brief history of "issues":
About a month or so into ownership... my fan, one day, decided to suddenly spin up to full RPMs and stayed at that speed for an eternity. I'm used to the fan speed steadily going up in direct relation to the CPU temp. However, the CPU temp this time was 35C the entire time (according to iStat Menus)... i.e. the MBA was "stone cold". It made no sense for the fan to be on full-blast. In addition, I had nothing running. No intensive software. Not even Safari. Just "Finder". Turning the MBA off naturally caused the fan to stop. However, the moment I powered it back on again, the fan came back on at full speed again.
An SMC reset fixed the issue, and I was good to go. This issue occurred again a few months later, but I solved it right away with the SMC reset.
After another month or so I noticed, while listening to music via headphones that were plugged into the MBA, that I could hear an electric "hum" in the headphones. Then all of a sudden the hum went away. I discovered that the hum was present only when I physically touched the metal case of the MBA and went away as soon as I removed my hand. I mentioned this to a Genius bar... err... genius and he seemed perplexed. He wasn't able to offer an answer.
I've also noticed that when the MBA is charging, and I run my finger-tips over the MBA's metal surface that I feel static. When the charger is unplugged, I no longer feel the static. Again the genius didn't have an answer. He probably thought I was weird.
I'm thinking my MBA might have "grounding" issues, but am no expert in this field. With the latest charging issues, however, I'm leaning towards this theory again.
Thoughts are welcome.
Regards
MrAirNo clues, it is very apparent you have a hardware problem and it is not the battery. If it was the battery the computer would not be running as you say the charger is not charging the battery.
There is a charging curcuit that has more then likely failed. You have done the correct thing, take it in and get it fixed before your warranty runs out. -
How to diagnose flickering exported JS animations from Flash CC?
Quick stats on my system:
Macbook Pro Retina 2012 running OSX 10.9.3
Flash CC 13.1.0.226
I'm not experiencing an error so much as a lack of understanding about how to diagnose Flash CC JS export issues. Here's the backstory:
In 2012, my company started working with an contract sprite artist. I was using the CS5.5 Creative Suite, and we were exporting normal png sequences from Flash for use in the game. After about 8 months, my cofounders and I realized that we could both reduce the load time for the game and also allow our artwork to be dynamically scalable by switching to JS exports of our art rather than the raster sprite sheets. Here's the blog post we wrote about it: http://blog.codecombat.com/hacking-our-way-to-vector-artwork-in-html5
At the time, I didn't have Flash CC, and was reliant upon the CreateJS plugin to export the required JS files: CreateJS Developer Center | Adobe Developer Connection After another month or so, our contractor upgraded their version of Flash and we started having compatibility issues reading FLA files, so I upgraded as well. After doing some reading, I concluded that the CreateJS plugin was now incorporated into Flash CC as the HTML5 doc type, which was confirmed when I checked out the publish settings and resulting files.
This is all a rather long winded way of saying that we have legacy artwork created with an older version of Flash but are now importing all of our artwork from JS files.
Fast forward to today and we have two big issues:
1) We can't figure out how to reduce the filesize of JS exports. As discussed in our blog post, vector artwork has upsides and downsides. One of the downsides we've found is that complex art that uses a lot of shapes ends up being substantially larger (in terms of filesize) than the appearance might otherwise suggest. Raster exports skirt this because a pixel is a pixel, but vector exports scale with the complexity of the source FLA. I'm not a Flash expert, and when we get files that are particularly complex, Flash either runs out of memory exporting them to JS files or we get files that are far too large to reasonably use. To be clear, the "out of memory" error isn't a problem because even if Flash finished the export, the resulting files would be too large for us to use (plus, I've done some digging and found a tutorial for correcting the out of memory error). Our artist is not familiar with the intricacies of the JS Flash exporter, so when we get a file that's too big or breaks the export, neither of us can really figure out a way to correct the problem. We have three questions in particular:
a) Where can you view shape data that Flash is going to write to the JS files?
b) Is there any way to edit said shape data inside the Flash CC interface?
c) Is there any way to optimize shape data in Flash? For instance, in Photoshop, you can flatten images and export a psd with 500 layers as a single JPEG, is there any way to do something similar to shape data in Flash?
2) Exports frequently break in weird ways. Many of the sprites that we created a year ago haven't needed to be re-imported into our game engine for some time. But every once in a while, I need to go back and fix, improve, or tweak an existing sprite, and then I run smack into the issue of reconciling files that were created without thought to JS exports with our current system. Just last week I was running into this issue in a big way and I made a screencast for our artist (since we work remotely) that I hoped might give him a better idea of the problem: Flash Errors - Treasure Chest, Flippable Tile - YouTube
The two files mentioned in that screencast are both old (treasure chest) and new (flippable land tile). We have a few questions:
a) Why are the treasure chest frames "flickering" in the html5 preview? The problem doesn't appear inside Flash and is inconsistent between files. There are two FLA files: one in which the treasure chest is empty, and one in which it's full. The empty animation doesn't throw any errors, either when converting to the HTML5 doc type or on export, but the resulting animation flickers. The full treasure, on the other hand gives me 21 lines of these errors when I do the conversion (not when I export): "Blend Modes(Layer) is not supported in HTML5 Canvas document, and has been converted to Normal in an instance of Movieclip <Path>." The result in both cases is the same: the animations flicker, and neither our artist nor us can figure out why, or for that matter, even begin to troubleshoot it. This SO issue seems to describe the problem, but was never resolved, and I can't find anything else that seems to address it: CreateJS Publish of Flash Project Flickers - Stack Overflow
I've uploaded the files involved to a public dropbox folder which I think you'll be able to access (Dropbox seems to be having some problems at the moment): Dropbox - flash_debugging
Since my questions are fairly involved, and my goal is to gain a better understanding of the UI, not simply resolve an error, I'd be happy to pay for someone's expertise/time in getting me up to speed. You can get in touch with me at george [at] codecombat.comHi George,
I have taken a look at the files full_treasure_chest.fla and flippable_land.fla that you have shared via drop box and found that they both uses blank keyframe(s) followed by Keyframe(s). This was an issue and has been addressed in the latest release Flash CC 2014 (released on 18 June, 2014). Can you please install the latest build 14.0.0.110 and try this out?
Thanks!

How to diagnose software / driver / video card issue?
My computer has been freezing up on a regular basis for the past few weeks . . .
I initially assumed it to be a bad stick of RAM, but I was able to reproduce the lockup with each stick individually.
I tried downgrading the kernel (but not Xorg or nvidia drivers), and that didn't fix anything.
At this point I don't really know enough (especially related to Arch specifically) as to how (which) log files to check for a reported error and issue.
The main issue of locking up occurs when I'm watching something on VLC at full screen. It's exacerbated with browsing or doing other stuff at the same time.
After a lockup I don't know if I should be checking journalctl / dmesg / Xorg.log / htop / etc . . .
Any advice / direction of stuff I can be checking after a crash would be MUCH appreciated. It really sucks not being able to use my PC like I used to.
If it help any my board/RAM are ~6yrs old, but the gfx card is new as of this year (I am using the regular nvidia drivers and multilib): EVGA 02G-P4-2645-KR GeForce GT 640

I tried various video drivers; nvidia 304, 325, 331 and nouveau, but in any case the system freezes after playing video for half an hour or so. The problem is more rare on a 32 bit installation than 64 bit, so perhaps you could move from 64 to 32 bit?
sorry for your troubles! i am not sure what the exact issue is, but i am on nvidia w/ video troubles as well . . . i have been running atop 24/7 and notice high r/w use of my disk at times when playback starts to stutter . . .
i haven't had a full-on lockup in days, but have still had one in recent time. i am not really sure how to trouble shoot this further. -
Re: javax.faces.convert.Converter error, how to diagnose?
I’m rendering a region on a page. The region is a table which is entirely build in java. The .jsff for the region looks kind of like this:
<af:treeTable value="#{backingBeanScope.myBean.treeModel}" var="row" etc…. >
<af:forEach items="#{backingBeanScope.myBean.columns}" var="column">
<af:column binding="#{column.adfColumn}" />
</af:forEach>
</af:treeTable>
When a row selection happens, there is context menu build, where one of the menuitems pops a dialog. After the dialog is dismissed a return handler/listener is called:
public void propertyToolReturnHandler(ReturnEvent event)
AdfUtil.showMessageDialog(AdfUtil.MESSAGE_TYPE.INFORMATION, “some msg”, “some msg”, true);
Notice the last param to showMessageDialog, which is “true”, as I want to show the message as inline. However, having it set to “true” causes the following exception. If I set it to “false”, then it does work and a popup message appears with the “some msg” text.
I’m truly stuck trying to figure out what Converter is missing and where. Any ideas will be most welcomed!
The error I get:

Edited by: user12869467 on Apr 12, 2013 1:57 PMI did more trial/error with this problem. It is not related to AdfUtil.showMessageDialog().
My java-built table, shows a popup. After the popup is dismissed, I will get this exception, not right away though. The view has tabs, if after dismissing the dialog, I navigate to some other tab, and then back to the one which has the table, that is when the error shows up.
ANY help on how to diagnose this problem will be very much appreciated!

How to diagnose HTTP 500 Internal Server Error
Hi all,
I have installed SSM 7.5 SP05 Hot Fix 1 on a Windows 2003 Server (64 bits), but in the End User Interface, the Home and Strategy tabs always shows an HTTP 500 Internal Server Error, how can diagnose this kind of error in order to solve this problem? Other tabs, for example the Initiatives tab works fine, the problem is only with the Home and Strategy tabs.
Thanks in advance.
Best Regards,
DouglasHi Ricardo,
After configuring the model connections all is working fine, thank you!
I have the idea that in previous versions that is not needed and just affect the Scorecard tab, now I know that if affects other tabs too, however, instead of HTTP 500 error would be more helpful another message that suggest the configuration as a requirement.
Again thanks for your help.
Best Regards,
Douglas -

I ran my multi-threaded application and ended up getting this output. my cpu % shoots up to 95% some time after starting my program. Also, I'd like to know how to debug, diagnose multi-threaded application in general. How to do C like trace and other means. Use a profiler. There are many different ones.
Exception in thread "main" java.lang.OutOfMemoryError: Java heap spaceThis indicates that you are either allocating too much memory, or are leaking memory. The VM will usually consume much cpu just before an OutOfMemoryError due to lots of call to the garbage collector.
Use a memory profiler to see why, and where the problem is. -
Satellite M30: Blue screen error - how to diagnose what it is?
I have a hardware problem but I am not sure of the exact nature. Although I looks like the hard drive or something communicating to it.
Some two weeks ago I started to notice performance problems when loading something from the internal hard drive: overall function of the computer (like mouse cursor movement, mp3 playback) became hampered when the harddisk was loading (saving was less of a problem).
This was NOT the case when loading data or executing programs from an external usb harddrive. Today I got a blue screen informing me that this crash was probably due to new hardware or software, followed by a physical memory dump and a harsh shutdown. I rebooted the computer, but got the same problem after the login screen.
Trying to start it up in safe mode didn't work either and after a couple of tries it never got to the login screen anymore -- a few seconds after boot start there was a flash of a blue screen followed by an immediate shutdown.
Anyway, I used the product recovery dvd-rom but the problem is still there, i.e. I can boot now but I get the same blue screen every hour at least (seems to correlate with usage).
Instead of running off to buy a new harddrive I want to be sure that that is the (only) problem, and not some motherboard issue or what have you.
Hence my question: how can I diagnose what's wrong with my notebook?Generally the best way is if you have a friend with the exact same portable. You can then take out your ram, and try it in their notebook, and try their ram in yours. If the problem persists on their computer, and yours boots up, its the ram. If not, the ram is fine. Then do the same with the HDD, again, if the problem doesnt happen on your computer, but happens on theirs, the HDD is bad, if not, your either down to CPU or Motherboard. A general overheating CPU goes into protection mode and automatically shuts the computer off. You dont get an error with overheating. But if the CPU has problems processing information it can generate blue screens. One sure way to find out if the CPU is defective is to continously reboot the computer and note the blue screen STOP error. If it remains the same constantly, then it is likely not the CPU, but the Motherboard. If it constantly changes from one error to the next, and generates 3 or 4 different errors, then you likely have a bad CPU.

Windows 7. How to diagnose 0x80070002 error.
Hi There
I'm having trouble tracking down the cause of this error when I try to setup a backup. I need help. I get the error when I open Backup and Restore and choose Set up Backup. If I choose my backup location (in this case a SanDisk, though a network drive yields the same error), click next, Allow Windows to choose the files, click next, click Save Settings and Run Backup, I immediately receive the 0x80070002 error (The system cannot find the file specified), as if Backup cannot find the location where it will save the specified settings. No error is subsequently found in the Event Log.
I can do a full system backup without problem.
I was having the same problem before upgrading from Vista to Windows7 (one of the reasons I chose to upgrade).
I'm looking for a solution or some help diagnosing this problem. I really dont want to do a full system backup every day.
ThanksOffline follow-up with Phillip revealed a problem with registering the scheduled task for backup which causes the Backup Configuration to fail. We have a couple of reports of this issue from users who upgraded from Vista to Win7.
We are sorry for the incovenience. Deleting Windows Backup scheduled tasks and then running backup again should solve the issue. Following steps describe how:
1. Launch Task Scheduler
2. Navigate to "Task Scheduler Library"\Microsoft\Windows\WindowsBackup
3. Delete tasks AutomaticBackup and Windows Backup Monitor
4. Retry configuring Backup.
It is possible that the tasks cannot be seen via the task scheduler UI. In that case:
1. Launch regedit
2. Delete the following keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows\WindowsBackup\ Windows Backup Monitor
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows\WindowsBackup\ AutomaticBackup
3. Retry Backup Configuration.
Thanks,

How to diagnose rapid memory growth in Solaris 10 java server application
Hi,
We have a production java based server that experienced large memory growth recently and we are looking for help in diagnosing what might be the cause. The memory footprint of this java server application is limited to 120M using the jvm -Xmx switch. The server process size held consistently at around 180M until an event happened that caused the process size to rapidly increase to aprox 3G. We used the java jstat command to check the application heap usage within the jvm was within the specified limits.
This application can be performs java Runtime exec's to run simple shell scripts from a variety of java threads in the server app.
We have attempted to search for a cause by analysing the output of the pmap, pfiles, and pstack commands but have been unsuccessfull at this. We have also attempted to run the libumem.so library with the application in the hopes of using mdb to find out where the heap usage is. Unfortunately when we followed the instruction on using limumem the application stopped working due an ELF error.
The following are what we used for libumem:
LD_PRELOAD=/usr/lib/libumem.so
UMEM_DEBUG=default
UMEM_LOGGING=transaction
export LD_PRELOAD UMEM_DEBUG UMEM_LOGGING
<run the application>
The error we got is:
ld.so.1: nohup: fatal: /usr/lib/libumem.so: wrong ELF class: ELFCLASS32
We are looking for advice on how to proceed in finding the cause for this growth. In addition to the diag info below we have captured the core file for the application from gcore. The following is the output from pfiles, pmap, pstack, and the showrev command.
Any help/suggestions appreciated.

SOCK_DGRAMI was finally able to reproduce this problem where I observed that within a 5 minute time span the jvm process grew from around 180M (VS) / 100M (RSS) to 2G (VS) / 1G (RSS). Here are some samplings at the end of my dtrace run showing the largest allocations that were made. We suspect this might be a JVM bug (since jstat reports our heap is well below the 120M limit we specified). Do you have any suggestions on how we might resolve this issue ?
Thanks,
Steve

How to diagnose performance problems?
Hi all,
I'm trying to run some basic performance tests of our app with Coherence, and I'm getting some pretty miserable results. I'm obviously missing something very basic about the configuration, but I can't figure out what it is.
For our test app, I'm using 3 machines, all Mac Pros running OSX 10.5. Each JVM is configured with 1G RAM and is running in server mode. We're connected on a gigabit LAN (I ran the datagram test, we get about 108Mb/sec but with high packet loss, around 10-12%). Two of the nodes are storage enabled, the other runs as a client performing an approximation of one of the operations we perform routinely.
The test consists of running a single operation many times. We're developing a card processing system, so I create a bunch of cards (10,000 by default), each of which has about 10 related objects in different caches. The objects are serialised using POF. I write all these to the caches, then perform a single operation for each card. The operation consists of about 14 reads and 6 writes. I can do this about 6-6.5 times per second, for a total of ~120 Coherence ops/sec, which seems extremely low.
During the test, the network tops out at about 1.2M/s, and the CPU at about 35% on the storage nodes and almost unnoticeable on the client. There's clearly something blocking somewhere, but I can't find what it is. The client uses a thread pool of 100 threads and has 100 threads assigned to its distributed service, and the storage nodes also have 100 threads assigned to their distributed services. I also tried giving more threads to the invocation service (since we use VersionedPut a lot), but that didn't seem to help either. I've also created the required indexes.
Any help in diagnosing what the problem would be greatly appreciated. I've attached the config used for the two types of node below.
Cheers,
Colin

</cache-config>Hi David,
Thanks for the quick response. I'm currently using an executor with 100 threads on the client. I thought that might not be enough since the CPU on the client hardly moves at all, but bumping that up to 1000 didn't change things. If I run the same code with a single Coherence instance in my local machine I get around 110/sec, so I suspect that somewhere in the transport layer something doesn't have enough threads.
The code is somewhat complicated because we have an abstraction layer on top of Coherence. I'll try to post the relevant parts below:
The main loop is pretty straightforward. This is a Runnable that I post to the client executor:
public void run()
Card card = read(dataManager, Card.class, "cardNumber", cardNumber);
assert card != null;
Group group = read(dataManager, Group.class, "id", card.getGroupId());
assert group != null;
Account account = read(dataManager, Account.class, "groupId", group.getId());
assert account != null;
User user = read(dataManager, User.class, "groupId", group.getId());
assert user != null;
ClientUser clientUser = read(dataManager, ClientUser.class, "userId", user.getId());
HoldLog holdLog = createHoldLog(group, account);
account.getCurrentHolds().add(holdLog);
account.setUpdated(now());
write(dataManager, HoldLog.class, holdLog);
ClientUser clientUser2 = read(dataManager, ClientUser.class, "userId", user.getId());
write(dataManager, Account.class, account);
NetworkMessage networkMessage = createNetworkMessage(message, card, group, holdLog);
write(dataManager, NetworkMessage.class, networkMessage);
read does a bit of juggling with our abstraction layer, basically this just gets a ValueExtractor for a named field and then creates an EqualsFilter with it:
private static <V extends Identifiable> V read(DataManager dataManager,
Class<V> valueClass,
String keyField,
Object keyValue)
DataMap<Identifiable> dataMap = dataManager.getDataMap(valueClass.getSimpleName(), valueClass);
FilterFactory filterFactory = dataManager.getFilterFactory();
ValueExtractorFactory extractorFactory = dataManager.getValueExtractorFactory();
Filter<Identifiable> filter = filterFactory.equals(extractorFactory.fieldExtractor(valueClass, keyField), keyValue);
Set<Map.Entry<GUID, Identifiable>> entries = dataMap.entrySet(filter);
if (entries.isEmpty())
return null;
assert entries.size() == 1 : "Expected single entry, found " + entries.size() + " for " + valueClass.getSimpleName();
return valueClass.cast(entries.iterator().next().getValue());
write is trivial:
private static <V extends Identifiable> void write(DataManager dataManager, Class<V> valueClass, V value)
DataMap<Identifiable> dataMap = dataManager.getDataMap(valueClass.getSimpleName(), valueClass);
dataMap.put(value.getId(), value);
And entrySet directly wraps the Coherence call:
public Set<Entry<GUID, V>> entrySet(Filter<V> filter)
validateFilter(filter);
return wrapEntrySet(dataMap.entrySet(((CoherenceFilterAdapter<V>) filter).getCoherenceFilter()));
This just returns a Map.EntrySet implementation that decodes the binary encoded objects.
I'm not really sure how much more code to post - what I have is really just a thin layer over Coherence, and I'm reasonably sure that the main problem isn't there since the CPU hardly moves on the client. I suspect thread starvation at some point, but I'm not sure where to look.
Thanks,

System crashes, even after clean install. How to diagnose?
Hi all,
Have been experiencing weird errors with my 2010 MBP, among which infrequent system crashes. I've seen my MBP swallow keypresses of the external Logitech keyboard I use. Replacing it with another (similar) model didn't help. It was getting quite annoying and I was beginning to distrust my Mac. I work on that, so it's crucial I have it running well.
After doing a complete clean install yesterday, the system crashed after 10 minutes of use. I'm suspecting a drive problem. I replaced the internal drive by a Crucial 256GB SSD a year and a half ago. I've already asked Disk Utility to do a check of the disk, but it reports no problems.
My system is now completely clean, but it's still not stable. How can I diagnose my MBP's issue?
Look forward to hearing from you,
MartinOk, adding some info as requested in other posts. Hope anyone can make something useful from this. The crash after 10 minutes of running was a kernel panic. It says page_fault now that I look at it in some detail. Is that a memory thing?
