Segmentation Error Java
We encountered for the second time this exception : Unhandled exception Type=Segmentation error vmState=0x0005ff0c ... Look at what libraries you are using and what native calls they might be making. I don't know - or at least cannot remember - what options there are to control the size of the stack for the main thread when AIX launches a process. Catalina.out or logs in the /var/log/messages may contain: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0xfe9bb960, pid=20929, tid=17 # # Java get redirected here
My guess (and it's only a guess) is that your code breaks the stack and you just happened to get away with it on other JREs.

Java Segmentation Fault Core Dumped
Your code assumes that you can arbitrarily allocate huge arrays on the thread stack without taking special action. But we haven't had a chance to upgrade yet. Any ideas what might be causing this, or is it possible to catch the exception to avoid the JVM crashing? It could also be due to a misconfiguration where incompatible components are used together.
As far as I can see, the only runtime issue here is the inaccuracy in the documentation of the -Xoss commandline option.

You are exceeding the stack size on a thread and it is failing. Reducing the max heap size from 16G to 10G after a fresh analysis in the profiler (which gave me a heap usage flattening out at 8G) did lead to a significantly I'm at a loss. useful reference Open Source Communities Subscriptions Downloads Support Cases Account Back Log In Register Red Hat Account Number: Account Details Newsletter and Contact Preferences User Management Account Maintenance My Profile Notifications Help Log

It is a VM bug. Check CONF-19049 for further information and user contributions. However, here goes. Segmentation Fault In C Crashes are often caused by JDK bugs that get fixed over time.
just plain JDBC with bouncycastle on JDK 1.6.. There definitely is enough memory available, and when I last checked in the profiler, heap usage was around 50% with occasional spikes around 80%. There could be a bug in the JVM itself, or in a package (some of these are written in C or C++). this page 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
However, I would guess you have some JNI bug. How to apply a constant function to a vector of values? I would expect to see such faults in C or C++ programs, but in Java since there are no pointers , how is segmentation fault possible. Yes No Thanks for your feedback!

Use gdb to investigate If you've really managed to make the JVM take a sigsegv without any native code of your own, you are very unlikely to make any sense of
