Browse other questions tagged java linux or ask your own question. I suspect that simply moving your "main" processing to a java created thread would be enough to address your problem, by allowing you to control the stack size appropriately. I could argue that the behaviour with the old runtime was unlucky as you didn't get feedback quickly enough that your native code was badly behaved. As I'm getting the crashes during GC, I'll try switching between garbage collectors.

See http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.genprogc/doc/genprogc/thread_lib.htm&tocNode=int_12876 for some discussion of thread stack sizes. Regarding the PMR: it appears that we do not have a support contract for Java and thus cannot raise a PMR. But i do not find any file indicating the reason for termination in the current user directory from where the program was run.

Though I'm not so far able to reliably reproduce the event, it does not seem to occur entirely at random either, so testing is not completely impossible.

That is irrelevant. http://internetmairie.com/segmentation-fault/segmentation-fault-core-dumped-centos-6.html That you've not failed on previous JVMs is not relevant - you've simply been (un)lucky before. The real use of the JNI interface accesses much more code (the compiled libraryr has a size of nearly 80MB), so you cannot know where this problem would strike again. Initialize last array?

Cannot patch Sitecore initialize pipeline (Sitecore 8.1 Update 3) Can a secure cookie be set from an insecure HTTP connection?

As far as I can see, the only runtime issue here is the inaccuracy in the documentation of the -Xoss commandline option. Hi Mark Thank you for your elaboration. Or is it just that the way the J9 JVM sets up the main thread in a static way with a smaller stack size and we will have to live with Segmentation Fault In C Linux ps -aux | grep java Windows Hit ctrl-alt-delete and check for java.exe in the running programs.

The -Xmso option to the JVM may help, but I'm not holding out that much hope. They are working on reproducing the issue in their lab and will let me know when a solution becomes available.  dcabasson 2 Joined: Jun 2 2010 - 5:36pm Last seen: 6 Learn More Red Hat Product Security Center Engage with our Red Hat Product Security team, access security updates, and ensure your environments are not exposed to any known security vulnerabilities. navigate here Look at what libraries you are using and what native calls they might be making.

Please enter a title. I am not sure whether it is because of some memory shortage or something else, but that is taking the server down pretty hard. Peter - thanks for that clarification. Hi Christoph, The documentation for the -Xoss option may be slightly misleading.
