#216 closed defect (invalid)

INI file corruption after running Java app (JavaRDP) for extended period

Reported by: Lewisr Owned by:
Priority: minor Milestone: Enhanced
Component: general Version: 1.6.0 Build 27 GA5
Severity: medium Keywords: INI write corrupt shutdown

Description

Likely due to memory fragmentation. I know that the condition is triggered by running JavaRDP for extended periods along with my other mix of apps.

The symptom is that after JavaRDP has been running for several hours, even if SeaMonkey? has been shutdown and restarted a few times, shutting down gets me all the way to the point where the desktop closes, and then I get a message that changes could not be saved to the INI files, and a prompt (by XWorkplace) to restart the desktop and use the standard shutdown routine. This never works, as invariably, the files cannot be written.

A reboot (even when not saving the files) generally results in either irreparable desktop damage (broken folder positions, file handles, etc.) or the system cannot even locate the desktop directory (even with SET DESKTOP set in CONFIG.SYS and valid EAs on the desktop directory). In these cases, a restore from an archive is the only recovery.

Please let me know what I can provide (some utility to track the fragmentation? Theseus output?) or perhaps what memory setting I might try when starting the JVM to avoid the situation. This seems to have started around GA4, but possibly earlier.

VIRTUALADDRESSLIMIT is set at 1576, but I have tried higher values with no discernable change.

Thanks for the report! The request is the same as in #65: please try to find an OpenJDK release that works for you as this may help us in finding the reason.

Also a question: do you use the Java or the Flash plugin in SeaMonkey? when it happens?

It's hard to tell what's running in SeaMonkey?, though it's entirely possible that Flash is loaded for something. SeaMonkey? is started from a batch wrapper:

:END

(Some of the above is quite old and should probably be removed or better commented, but you can see what's active and what's not.)

I'll also see about getting a few snapshots from about:memory.

Now, I can tell you that my brother's system is almost identical to mine, except that I know I do not have IcedTea? installed for him (though his Flash is at the same level as mine: Version: 0.4.1.0 - Shockwave Flash 11.5 r502).

I will uninstall IcedTea?, now that I've rolled the JVM back to GA3, and see what I get (this may impact results in #65, as well).

  • Resolution set to invalid
  • Status changed from new to closed

Time to close this. After finally spending some quality time with my desktop, the issue was apparently lack of attention (read: INIs got way too big, and this is the same old out-of-memory issue we see with a lot of things). So, a good cleaning, a diet, a few hundred KB off of their enormous size, and I no longer see this issue (thankfully).

Sorry for the bother!
