Tomcat crash: There is insufficient memory for the Java Runtime Environment to continue

问题:

We are running a webapplication with low number of users, about 7, but with high load of showing images. Recently we upgraded to Java 6u43 and Tomcat 6.036 and after some usage (about a week) tomcat services crashes. After a restart it can run for a few days, or just a few hours and crashes again. Even after reboot of the server it crashes again, we even saw that after 10 minutes of being active.

it is always with the same message in a hs_err_pid file in the bin folder of tomcat. See below an example of the full error message. It is always insufficient native memory and the main active thread is always JavaThread "C2 CompilerThread1", but always in a different method.

We are running on windows 2008 service pack 2, 32 bit, 2 CPU, 3GB. For tomcat xms set to 512KB and xmx to 1536KB. no other specific settings. When it crashes the Java heap is far below full usage of the 1536.

Any idea, suggestions what this could be?

(before the tomcat upgrade we used tomcat 6.014 and Java 6u02 for long time without any issue)

回答1:

The process heap != the java heap.

On 32-bit Windows you have (unless you set some boot switches) a 2GB maximum per process. This 2GB has to support:

• Java Heap (set with Xms, Xmx)
• PermGen
• Thread stacks
• GC
• Code cache
• Native JVM code

and probably a couple of things I have forgotten.

If the total of all of the above exceeds 2GB the process crashes. This is what has happended in your case.

The error message tells you quite clearly what you need to do. Pick one of the options and implement it.

Use a profiler like VisualVM. Connect it to monitor the memory use of your tomcat server (remote configuration). It will constantly monitor and show you your heap allocation. You can also see the objects being hold in memory.

If this happens you have either hit the memory limit of the process (you will see the total used amount in visual vm). It might be even a memory leak or a bug in the JVM. Check if you are using the 64 bit version. But first check out the object creation and heap using VisualVM (or similar). You can tell by the graph if your consumption goes up in a different way.

You can even compare the heap usage pattern you gain using the previous used Java version. This way you can compare the memory consumption of the old working setup with the new problematic one.
