The application is basically a Servlet on top of Apaches Tomcat 8 and crashes every 3 to n days. The most interesting part is, that the last 3 crashes happened at 1.30 PM + 3 to 4 seconds. Every other crash happens at 15, 30, 45 or the full hour. The same application worked for months on Windows 7 with Java 7 something.
I found this report so I checked the available space at /tmp and I have plenty of space here. However, the next time I ran the VM with:
-XX:-UsePerfData
-XX:+PerfDisableSharedMem
and the hsperfdata file is no longer written but the problem persist. According to this report PerfData might be still used to some extend even if it is disabled.
It seems to be this piece of code:
void PerfLongVariant::sample() {
// JJJ - This should not happen. Maybe the first sample is taken
// while the _sample_helper is being null'ed out.
// assert(_sample_helper != NULL || _sampled != NULL, "unexpected state");
if (_sample_helper == NULL) return;
if (_sample_helper != NULL) {
*(jlong*)_valuep = _sample_helper->take_sample();
}
else if (_sampled != NULL) {
*(jlong*)_valuep = *_sampled;
}
}
I assume the problem occures here:
*(jlong*)_valuep = _sample_helper->take_sample();
but I am not sure which implementation is used at runtime:
statSampler seems unlikely as I don't see the connection to elapsed_counter except for the above mentioned phenomena with the crash time.
/*
* helper class to provide for sampling of the elapsed_counter value
* maintained in the OS class.
*/
class HighResTimeSampler : public PerfSampleHelper {
public:
jlong take_sample() { return os::elapsed_counter(); }
};
or gSpaceCounter
inline jlong take_sample() {
return _gen->used();
}
and spaceCounters and cSpaceCounter I have the impression that the size of one of the pools in the Java memory pool is returned before it is updated. Which ultimately lead to SIGBUS 7, bad memory access.
What are my options?
The last crash report (dynamic libraries removed):

Based on the output from !vmstat, you are out of memory. There's some mild address space fragmentation, but you only have a total of ~350MB of free memory, so you're really running close to the address space limit. The largest free block is just 6MB, and the CLR allocates virtual memory segments that are at least 16MB in size.
Your total GC heap size is just 470MB (see the last line from the !eeheap -gc output), which means you have other stuff in your process using up address space. Namely, you have >500MB of images (DLLs) and >3GB of memory classified as "Private". This can be a bunch of different things; for example, it can be unmanaged heap allocations.
You can try to further zoom in on the space hog by running !heap -s -h 0 to see if you have large unmanaged heaps in your process. I suggest that once you have a direction (is it an unmanaged heap leak? something else?) to ask another question with your findings. From the information you posted so far, we can conclude it's likely unrelated to what the managed part of your application is doing. Do you have large unmanaged components in your application? There are techniques for analyzing unmanaged memory leaks, such as UMDH or ETW heap allocation tracing.
One final comment: why are you running a 32-bit app on a system with 32 processors? Looks like a server system, and I bet you have more than 4GB of physical memory. If it's at all under your control, try making the move to 64-bit.
We have a java application that calls a native method from a dll. This works for us most of the time but very rarely on some pcs the JNI is calling wrong native method. As we have finally a machine that reproduces the issue regurally we would like to investigate what is the reason and hopefully fix it, but we are out of ideas how to investigate the issue.
The following is a java crash dump. It is visible there that we are trying to invoke method setVolumeNative; the method create is invoked however.
We would expect to see the following on stack:
Java_net_inspiredbroadcast_legion_jni_volume_MainVolume_setVolumeNative
But we see there this:
Java_net_inspiredbroadcast_legion_jni_process_ProcessImpl_create
