Background: Since the past few days, my linux development machine Java services one by one by the system kill, I looked at the system logs are OOM caused. Now I can't start the java process if I set the initial heap too large.
I can't see with the usual troubleshooting means, the development machine is a virtual machine (I don't think I can exclude the problem of the physical machine where the virtual machine is located, my colleague's machine and I applied at the same time, also have this problem), the total memory is about 6G, buff/cache + free total of about 5G. Thank you all for your help.
The crash logs at startup are in the attachment, and the system information and jdk information are in there.

I have reached a problem where java virtual machine simply does not have enough memory to compile. What should I do about this?
The jvm is run by eclipse and it is already part of the 64 bit server. I am running approx 600 lines of code in one class with dependency on a few other classes with data read and saved in text file.
The error report is shown below
There is insufficient memory for the Java Runtime Environment to continue.
Native memory allocation (malloc) failed to allocate 1048576 bytes for

Possible reasons:
The system is out of physical RAM or swap space
In 32 bit mode, the process size limit was hit
Possible solutions:
Reduce memory load on the system
Increase physical memory or swap space
Check if swap backing store is full
Use 64 bit Java on a 64 bit OS
Decrease Java heap size (-Xmx/-Xms)
Decrease number of Java threads
Decrease Java thread stack sizes (-Xss)
Set larger code cache with -XX:ReservedCodeCacheSize=

I am working on a Spring-MVC application in which I am computing the statistics every night. The problem is, yesterdays computation failed and I have this error and an hs_err_something.log file. The file basically says Out of memory error, but our servers have 32GB ram and quite lot of disk space too. Also, the server is kind of relaxed in night. Why I am I getting this error. I will post contents of relevant code.
StatisticsServiceImpl :
#Override
#Scheduled(cron = "0 2 2 * * ?")
public void computeStatisticsForAllUsers() {
// One of the count as part of statistics
int groupNotesCount = this.groupNotesService.getNoteCountForUser(person.getUsername());
}
GroupNotesDAOImpl :
#Override
public int getNoteCountForUser(String noteCreatorEmail) {
Session session = this.sessionFactory.getCurrentSession();
Query query = session.createQuery("select count(*) from GroupNotes as gn where gn.noteCreatorEmail=:noteCreatorEmail");
query.setParameter("noteCreatorEmail", noteCreatorEmail);
return new Integer(String.valueOf(query.uniqueResult()));
}

For the record (and Google), this looks like both these bugs, which were fixed in the 1.6u22 release of sun's jdk. So, first thing to do is update your JVM. If it still happens, and always happens on a particular method, you can exclude that method from compilation (as long as you're aware of the performance implications of that) with the following jvm flag:
-XX:CompileCommand=exclude,org/apache/velocity/runtime/directive/Foreach,render
(as suggested here). But, first update your jvm.
You're running with a lot of JVM args that affect memory. Have you tried empirically removing each option to see which one is causing the OOM? This particular OOM is not coming from the Java heap, it's coming from the JVM's own C heap.
As stated by the other answers / comments, you are running out of memory. Given your JVM settings, I'd say that the root cause is 99% likely to be a memory leak.
If you have been doing a lot of hot loading in the Tomcat instance, this could just be caused by that. Hot loading is notorious for leaking memory, and there is not much you can do about it in practice ... except exit and restart your Tomcat more often.
The other possibility is that your application is leaking memory. If this is the case then you will need to use a memory profiler to track down the leak.
The fact that the OOME caused a JVM crash is interesting, but probably not significant. (It looks like the JVM was trying to JIT compile a class generated from a JSP when it ran out of memory. The chunk being requested is rather large, but that probably means you have a rather large / complicated JSP.)
