Secd Process Memory Leak
Finding the secd process using 13GB of RAM was a bit of a shock. Watching its RAM consumption continue to increase, indicates a memory leak. Is this something anyone else has noticed? And any possible solutions?
Thanks - I think this helped, but will give it a day or two to see what happens.
My secd was over 32 GB the other day and the iMac wasn't quite its usual self. After restarting, secd's memory usage dropped away, but has been steadily creeping up over the last couple of days and was over 5GB this morning. So I tried dragging the Keychains folder to the trash and restarting.
The thing about dragging your keychain to the trash and restarting is, on logging back in you may be asked for a pile of passwords to all your mail accounts and your keychain will be empty!
I filled out all the requests for icloud passwords, but for the keychain to update properly, this took a while. I think what saved me from panicking about losing all my passwords, was going into System Preferences and signing into iCloud there. I was also requested to verify my iCloud login from another device (e.g., iPAD). I think this is what restored my keychain from the cloud.
Once the keychain had updated itself, I restarted the iMac again, and Mail returned to normal (no more requests for mail account passwords).
The only thing that wasn't restored after restarting was automatic keychain access to my time machine. I had to enter the password and save it to the keychain.

Process memory leak issue solaris 10
I have a process which has a memory leak issue. I ran this process on solaris 9 as well as solaris 10. When i run prstat command i get a different output for two. Funny thing is that memory leak noted in solaris 10 is much more than that in solaris 9 e.g if it is 1 MB in solaris 9 then its 4 MB in solaris 10.
What can be possibly causing this ? Is this related to kernel implementation on diff solaris ?I have a process which has a memory leak issue. I ran this process on solaris 9 as well as solaris 10.

Safari web process - memory leak?
Mac Pro seemed to have slowed to a crawl.
Safari 5.1.2 on SL 10.6.8
Activity Monitor showed I was low on memory - over 7GB was being used by 'safari web process' - slowly close all open pages until only left with two - one was simply the 'bing' home page, the other a page that had failed to load.
Anyone else had this kind of thing recently?Safari has a known memory leak. Open teh Activity Monitor, sort the list of apps by Real Memory column. You will find one called Safari Web Content. This is the cause. If you are running an safari extensions, they use SWafari Web Content to run, you can try turning off your extensions to see if that helps. About the only know fix now, is to close safari regularly. 5.1.2 was suppose to close some leaks but has not. There are reports you can run safari in 32bit mode but I haven't confirmed if this helps or not.

I have been tracking down memory leaks in a Java server-based application. I recently ran the application for several hours, and monitored memory usage with both JConsole and the Unix �top� command. I encountered some behaviors that I don�t understand.
With JConsole, I observed that the heap memory usage was fairly constant over time. The Code Cache space, however, gradually increased in size over the life of the test. I expected some increase as additional methods in the application were executed, but it seems that eventually the rate of increase would level out. It did not. Any ideas why that might happen?
The resident memory (as reported by top) increased significantly over the life of the test. Using pmap and jmap, I was able to determine that the heap space was increasing (even though JConsole reported that the heap was constant.) So, it seems as though the heap usage of the application is constant, but the heap usage of the process is still growing? I am using Java HotSpot VM for Solaris (1.6.0-b105).
Any suggestions or insight would be appreciated.I'm not sure exactly what you're saying, but it sounds like this:
A tool that's monitoring the VM says the memory used by your objects is not increasing, but other tools say the memory the VM has taken from the OS is increasing.
Is that the case? If not, nevermind--I've misunderstood.
If that is the case, then it's totally expected. The VM doesn't usually give memory back to the OS. If it hasn't used up the amount specified by -Xmx (or the default if you didn't specify -Xmx), it's free to just keep grabbing memory from the OS, rather than running a full GC to reclaim memory that it has used for objects but that is no longer reachable. -
After 10.8.4....imagent process memory leak
I upgraded my MBA to 10.8.4. I started getting messages that my startup memory was full. I take a peak at Activity monitor and "imagent" is using 6GB of RAM and my HD has dropped in available space almost 100GB!!!
I force quit the process and reboot to recover the space soaked up by the leak, but it keeps coming back. As soon as I hear my fans going crazy I look at activity monitor and yep its back again.
Any one else with this issue after 10.8.4? I see in the release notes it was supposed to fix the reording of the messages in "imagent" but at this point I'll take the reorder problem over this problem.Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
Hi all,
Since using a beta a couple of times I've noticed that imagent has gone nuts and started swapping insanely. I have about 30Gb free on my system drive, and it will chew through it all in a matter of minutes, then bring the whole computer to it's knees.
If I catch it in time and kill the process I loose that diskspace to vmswap files, but will get it back on reboot, and I can keep using the computer. If not, I have to hard reboot.
Using 10.7.3, and the Messages Beta. I have a yahoo, AIM, and iMessage accounts.
Also, since killing off the imagent process and it going nuts, even after a restart of the Messages app, I can't iMessage people.
Anyone else seen any odd behaviour?
Regards,
AlexI also had Messages fail to deliver after killing imagent, and even after rebooting. Turns out in my case Messages had mysteriously switched to locating my contacts by email address rather than cell number. Switching contacts back to number made Message app resend failed messages successfully.

OBVIOUS MEMORY LEAK
iTunes about:10.6.3.25
windows 64 bit Home on AMD64 HP G60 laptop
downloaded and installed "iTunes32Setup.exe"
saw the problem and uninstalled it
downloaded and installed "iTunes64Setup.exe"
iTunes about:10.6.3.25
now i see process "iTunes.exe*32
it is ok when it play song list
but ***** UP MEMORY when i click on another song to play. apparently it doesn't release previous player thread
OR,
if you right click on a song, the memory will blow up antother 6MB and won't release it...can do it all day long
-- until run out of memory and iTunes freezes...without any of my changes.
sooooo.. is it the uninstaller or is iTunes64Setup.exe mispackaged or do both have memory problems on AMD 64 ?Unfortunately I was able to repeat the memory leak even with turning the Toolbar off. To replicate the problem, I was able to watch the memory leak each time I actively selected a new song with the iTunes open. I was able to repeat the leak with and without both Spotify and TuneUp Companion running and not running. The only thing I noticed is when both Spotify and iTunes were open, the memory leak from iTunes added insult to injure with Spotify which kept trying to sync up with iTunes local library which would crash Spotify as well. But I can confirm the memory leak is in iTunes 10.6.3.25 (looking forward to 10.6.4 fixing the problem).

Detecting a memory leak in a process running on Solaris 5.7
Hi,
Iam running my application on solaris 5.7 platform.
I can see clear memory leak in that process.
Is there any tool or in-built functionality on solaris 5.7 to detect/fix that leak.
Thanks in advance,
AvvaruThanks for the reply. I already turned it off in both Safari and Spotlight preferences. However the problem persists. The process still runs, and from time to time it decides to leak all the memory as well. I really can't understand what the reason might be.
To be clear, in Safari-->Preferences-->Search-->Smart search field-->"Include Spotlight Suggestions" is un-checked. In Spotlight preferences all three "Spotlight Suggestions", "Bookmarks & History" and "Bing Web Searches" are un-checked. Process still runs under Spotlight as can be seen here:
After the last post I let it run for a while when it happened again, and below is just before i terminated it. Look at the memory usage! -
XSLT processing and Memory Leak
I have the following code for a Simple XSLT Transformation from one form of XML to another, the Size of the XML and the XSLT file are very small( few KB).
As you can see I'm explicitly setting everything to null just to make sure the objects get GC'd.
When I run the transformation on my local m/c running Windows XP on WSAD5.0 there are no memory leak issues, but when I deploy the Same app on our Server running WSAD 5.1 on Solaris, I see memory issues and finally throws an OutOfMemory Exception.
Any Ideas would be appreciated.

All code work's as well, but i have a memory leak by using structure (by creating a new MyStructure());Presumably this really is java code. As such the following are the only possibilities
1. You do not have a memory leak. You are misreading a tool (probably task manager) and assuming a leak exists when it doesn't.
2. You need to call something either on MyStructure or by passing it to another class to free it. See the documentation.
3. The leak is caused by something else. -
ORA 04030 Out of process memory error
Dear experts,
I know there are multiple discussions around this error and I have been reading through most of them in the past one week or so, but looks like we are running out of options or are missing the color altogether. Ok, we are getting ORA-04030 - out of process memory while allocating....while one of our batch process runs in the night. It simply tries to insert/update to a table. Our installation is 11.2.0.1.0 with no RAC configuration and on 64-bit AIX having 6 cores, 12 CPUs and 16 GB memory.
We have checked the Workarea_Size_Policy is set to be as Auto so Oracle decides how much memory to allocate to PGA automatically on run-time based on the demand. And based on the AWR report it doesnt look like we are anywhere near the country having a PGA-deficit!! I am attaching the AWR report in a word document here for your reference.
Also attached below are the configurations and the ulimit values.
IKBTRN1> show parameter workarea;
NAME TYPE VALUE
workarea_size_policy string AUTO
oraipeikbtrn1:/home/oracle-> ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 4194304
memory(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimited
Now, nothing seems to have contributed to the out of process memory issue from Oracle standpoint. I would be happy to be proved wrong here, if I am wrong.
So, whats going wrong here? A possible memory leak which we cannot zero down to, a OS memory limit or something else?
Seeking expert's advise on this, and also sincerely appreciate your time in looking at this.
Thanks.
P.S - I am pasting the whole AWR report since there is no 'upload file' option here that I can see.

I couldnt add the rest of the report here since it is telling me I have exceeded 30000 characters. If you want to see the full report, please email me at [email protected]Unless your database is strictly a DSS-type of database, your AWR report exposes loads of issues with it. And I think none of the time during the AWR window was spent on database. Look at the DB time (with all those multi cores) compared with the elapsed time of the AWR.
As you are on 11g, why not make use of MEMORY_TARGET (a single parameter to manage both SGA and PGA)? If you are already on it, ignore this as I can't see it anywhere. If not, get rid of SGA_TARGET and PGA_AGGREGATE_TARGET and replace it with a single MEMORY_TARGET parameter. However you may have a minimum threshold set for different SGA pools so that they won't shrink beyond that point.
Having said that, setting MEMORY_TARGET is not a guarantee to avoid ORA-4030. Just a single bad PL/SQL code could go and exploit the untunable part of your process memory and even go and blow up the physical memory. If you are using FORALL and BULK load, see if you can cut it down into few chunks rather than running as a single process.

Memory Leaks Unresponsive Mouse
2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone). When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff). This machine worked just fine under OS 10.9 and earlier - no issues like this at all. ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up). I have to use Terminal to purge it so that the machine is usable.
The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond. The right button will open the right click menu, but will not respond normally at all. I have tried a different Magic Mouse, but the problem is the same.
I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together. So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed. All of the RAM also passes the memory tests in Rember and TechTool.
So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues. I also need to find out what is causing the memory leaks. I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to). It did nothing to fix the problem.
I need some guidance here. As I stated early on, the machine worked perfectly with OS 10.9. I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything. This problem is annoying and I know that I am not the only one having these issues. Any input will be greatly appreciated. Thanks in advance.Here is the EtreCheck report:
Problem description:
Memory leaks when using Toast 10 or Parallels 9. Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

T61 with memory leak on XP for driver battc.sys
Hi
I have an issue with XP where the battc.sys module that is part of Windows XP and responsible for the kernel side of monitoring the battery status. This module continually leaks memory until I have no more kernel paged resources left and programs start to fail on my laptop.
I raised a support case for this with Microsoft and after some investigation and upgrading to the latest T61 power drivers that were released a few days ago on the Lenovo site, MS support told me it is a fault of the T61 and that I would need to disable Microsoft APCI support to stop this memory leak from occuring and to take the issue up with Lenovo.
I have used the verifier tool to confirm that it is the Windows XP SP3 battc.sys memory module leaking.
I am running the latest T61 drivers and fully patch with MS drivers on SP3.
As MS have told me it is the fault of the T61 I am posting this issue here.
Thanks
StephenIt is memory available to the kernelwhich itself does not show under a process in task manager as far as I am aware (unles it is taken account as part of the system process).
The best way to measure the available kernel memory space available is by using sysinternals procexp.
You need to download procexp and also install the windows debugging tools from Microsoft. Then in procexp set the "Options > Configure Symbols : Debughlp.dll path" to the new debughlp.dll installed with your debu tools and set the symbols path to srv*c:\Symbols*http://msdl.microsoft.com/download/symbols
Then you can choose in procexp "View > System Information" and see the used and total paged and non-paged kernel memory space.
poolmon helps monitor all the symbols that are taking up this memory and verifier lets you drill down to the exact module and the changes in memory for a module that is occuring.
Here are two really good links on it
http://blogs.msdn.com/ntdebugging/archive/2006/12/18/Understanding-Pool-Consumption-and-Event-ID_3A0...
http://blogs.msdn.com/ntdebugging/archive/2008/05/08/tracking-down-mmst-paged-pool-usage.aspx
In my poolmon i notice that Mmst and battc are taking alot of memory after my computer has been running for some time. Mmst being high is normal but battc should not continually be growing as it is which is why I raised the case to MS but they want verification it is not a Lenovo issue. -
Pro*c multithreaded application has memory leak
Hi there,
I posted this message a week ago in OCI section, nobody answer me.
I am really curious if my application has a bug or the pro*c has a bug.
Anyone can compile the sample code and test it easily.
I made multithreaded application which queries dynamic SQL, it works.
But the memory leaks when i query the SQL statement.
The more memory leaks, the more i query the SQL statement, even same SQL
statement.
I check it with top, shell command.
My machine is SUN E450, Solaris 8. Oracle 9.2.0.1
Compiler : gcc (GCC) 3.2.2
I changed source code which is from
$(ORACLE_HOME)/precomp/demo/proc/sample10.pc
the sample10 doesn't need to be multithreaded. But i think it has to work
correctly if i changed it to multithreaded application.
the make file and source code will be placed below.
I have to figure out the problem.
Please help
Thanks in advance,
the make file is below

Sample Program 10: Dynamic SQL Method 4
This program connects you to ORACLE using your username and
password, then prompts you for a SQL statement. You can enter
any legal SQL statement. Use regular SQL syntax, not embedded SQL.
Your statement will be processed. If it is a query, the rows
fetched are displayed.
You can enter multi-line statements. The limit is 1023 characters.
This sample program only processes up to MAX_ITEMS bind variables and
MAX_ITEMS select-list items. MAX_ITEMS is #defined to be 40.

sqlprc() is used to extract precision and scale
from the length (select_dp->L).
sqlnul() is used to reset the high-order bit of
the datatype and to check whether the column
is NOT NULL.
CHAR datatypes have length, but zero precision and
scale. The length is defined at CREATE time.
NUMBER datatypes have precision and scale only if
defined at CREATE time. If the column
definition was just NUMBER, the precision
and scale are zero, and you must allocate
the required maximum length.
DATE datatypes return a length of 7 if the default
format is used. This should be increased to
9 to store the actual date character string.
If you use the TO_CHAR function, the maximum
length could be 75, but will probably be less
(you can see the effects of this in SQL*Plus).
ROWID datatype always returns a fixed length of 18 if
coerced to CHAR.
LONG and
LONG RAW datatypes return a length of 0 (zero),
so you need to set a maximum. In this example,
it is 240 characters.

Firefox memory leak, how to fix?
I've noticed i've been having memory leaks since quite a few versions before the latest one (33.1.1) and the problem still continues, i notice this more when i leave firefox open for awhile, sometimes only with youtube and couple of other "static" pages on, but i've got the same results without youtube.
Today i decided to ask the question, since i haven't seen any memory leak bugfixes in the recent changelogs and it becomes quite a problem to me because i leave it all day open and when it happens it forces me to restart (not really forces but i don't like having an 1.3GB process when i can have the same for 500~ ...)
I don't believe any of my extras are the reason for it, i've tested them over the pass'ed versions, removed a few, installed a few, always same problem.
All of this running WIndows 7 Ultimate 64-bits .
i've researched and found it's a "common" problem, but no really solution or expected bugfix soon or anything, i'm still to test it without any 3rd part extensions or plugins, but i don't (think) have any extensions that may cause this because like i said, i've changed them quite a few times.
Here is my extension list: http://i.imgur.com/Rk80ajU.png
Here is my plugin list: http://i.imgur.com/GBA0qgY.png
And here is a "Measure" report from "about:memory" : http://privatepaste.com/bcd17c1093
I just want to know why it leaks so badly, almost the double RAM it would normally use.
Currently i'm like 3 tabs with 1.25 GB (Private Set) used, when i close a few tabs, it keeps stable or even rising by a few mb.
I hope there's something useful with that report/my extensions|plugins.
Thanks for the reading.I heard about that extension "problem" but, when i see on "about:addons-memory" from a third-party extension (that i can't remember but yo can see it in the link on OP, it only uses few megabytes (20~) , so, either it's a memory leak on the extension (if that's really the cause) a problem with my addon to view the extensions memory or a firefox one.
But i seriously don't expect that extension eats up all of this memory, but i will test it in a couple of days. -
Memory leak using xslprocessor.valueof in 11.1.0.6.0 - 64bit ??
My company has made the decision to do all of our internal inter-system communication using XML. Often we may need to transfer thousands of records from one system to another and due to this (and the 32K limit in prior versions) we're implementing it in 11g. Currently we have Oracle 11g Enterprise Edition Release 11.1.0.6.0 on 64 bit Linux.
This is a completely network/memory setup - the XML data comes in using UTL_HTTP and is stored in a CLOB in memory and then converted to a DOMDocument variable and finally the relevant data is extracted using xslprocessor.valueof calls.
While this is working fine for smaller datasets, I've discovered that repeated calls with very large documents cause the xslprocessor to run out of memory with the following message:
ERROR at line 1:
ORA-04030: out of process memory when trying to allocate 21256 bytes
(qmxdContextEnc,)
ORA-06512: at "XDB.DBMS_XSLPROCESSOR", line 1010
ORA-06512: at "XDB.DBMS_XSLPROCESSOR", line 1036
ORA-06512: at "XDB.DBMS_XSLPROCESSOR", line 1044
ORA-06512: at "SCOTT.UTL_INTERFACE_PKG", line 206
ORA-06512: at line 28
Elapsed: 00:03:32.45
SQL>
From further testing, it appears that the failure occurs after approximately 161,500 calls to xslprocessor.valueof however I'm sure this is dependent on the amount of server memory available (6 GB in my case).
I expect that we will try and log a TAR on this, but my DBA is on vacation right now. Has anyone else tried calling the xslprocessor 200,000 times in a single session?
I've tried to make my test code as simple as possible in order to track down the problem. This first block simply iterates through all of our offices asking for all of the employees at that office (there are 140 offices in the table).
DECLARE
CURSOR c_offices IS
SELECT office_id
FROM offices
ORDER BY office_id;
r_offices C_OFFICES%ROWTYPE;
BEGIN
OPEN c_offices;
LOOP
FETCH c_offices INTO r_offices;
EXIT WHEN c_offices%NOTFOUND;
utl_interface_pkg.get_employees(r_offices.office_id);
END LOOP;
CLOSE c_offices;
END;
Normally I'd be returning a collection of result data from this procedure, however I'm trying to make things as simple as possible and make sure I'm not causing the memory leak myself.
Below is what makes the SOAP calls (using the widely circulated UTL_SOAP_API) to get our data and then extracts the relevant parts. Each office (call) should return between 200 and 1200 employee records.
PROCEDURE get_employees (p_office_id IN VARCHAR2)
l_request utl_soap_api.t_request;
l_response utl_soap_api.t_response;
l_data_clob CLOB;
l_xml_namespace VARCHAR2(100) := 'xmlns="' || G_XMLNS_PREFIX || 'EMP.wsGetEmployees"';
l_xml_doc xmldom.DOMDocument;
l_node_list xmldom.DOMNodeList;
l_node xmldom.DOMNode;
parser xmlparser.Parser;
l_emp_id NUMBER;
l_emp_first_name VARCHAR2(100);
l_emp_last_name VARCHAR2(100);
BEGIN
--Set our authentication information.
utl_soap_api.set_proxy_authentication(p_username => G_AUTH_USER, p_password => G_AUTH_PASS);
l_request := utl_soap_api.new_request(p_method => 'wsGetEmployees',
p_namespace => l_xml_namespace);
utl_soap_api.add_parameter(p_request => l_request,
p_name => 'officeId',
p_type => 'xsd:string',
p_value => p_office_id);
l_response := utl_soap_api.invoke(p_request => l_request,
p_url => G_SOAP_URL,
p_action => 'wsGetEmployees');
dbms_lob.createtemporary(l_data_clob, cache=>FALSE);
l_data_clob := utl_soap_api.get_return_clob_value(p_response => l_response,
p_name => '*',
p_namespace => l_xml_namespace);
l_data_clob := DBMS_XMLGEN.CONVERT(l_data_clob, 1); --Storing in CLOB converted symbols (<">) into escaped values (<, &qt;, >). We need to CONVERT them back.
parser := xmlparser.newParser;
xmlparser.parseClob(parser, l_data_clob);
dbms_lob.freetemporary(l_data_clob);
l_xml_doc := xmlparser.getDocument(parser);
xmlparser.freeparser(parser);
l_node_list := xslprocessor.selectNodes(xmldom.makeNode(l_xml_doc),'/employees/employee');
FOR i_emp IN 0 .. (xmldom.getLength(l_node_list) - 1)
LOOP
l_node := xmldom.item(l_node_list, i_emp);
l_emp_id := dbms_xslprocessor.valueOf(l_node, 'EMPLOYEEID');
l_emp_first_name := dbms_xslprocessor.valueOf(l_node, 'FIRSTNAME');
l_emp_last_name := dbms_xslprocessor.valueOf(l_node, 'LASTNAME');
END LOOP;
xmldom.freeDocument(l_xml_doc);
END get_employees;
All of this works just fine for smaller result sets, or fewer iterations (only the first two or three offices). Even up to the point of failure the data is being extracted correctly - it just eventually runs out of memory. Is there any way to free up the xslprocessor? I've even tried issuing DBMS_SESSION.FREE_UNUSED_USER_MEMORY but it makes no difference.Replying to both of you -
Line 206 is the first call to xslprocessor.valueof:
LINE TEXT
206 l_emp_id := dbms_xslprocessor.valueOf(l_node, 'EMPLOYEEID');
This is one function inside of a larger package (the UTL_INTERFACE_PKG). The package is just a grouping of these functions - one for each type of SOAP interface we're using. None of the others exhibited this problem, but then none of them return anywhere near this much data either.
Here is the contents of V$TEMPORARY_LOBS immediately after the crash:
SID CACHE_LOBS NOCACHE_LOBS ABSTRACT_LOBS
132 0 0 0
148 19 1 0
SID 132 is a SYS session and SID 148 is mine.
I've discovered with further testing that if I comment out all of the xslprocessor.valueof calls except for the first one the code will complete successfully. It executes the valueof call 99,463 times. If I then uncomment one of those additional calls, we double the number of executions to a theoretical 198,926 (which is greater than the 161,500 point where it usually crashes) and it runs out of memory again.
