Tomcat crashed when used with java

**Pikachoo** · 06-03-2009

Hello.

I developed a web application on apache tomcat. I noticed that often the application server crashes, displaying the tomcat log file:

Code:

It appears that there is an error in the memory of the JVM that causes the crash of Tomcat. Can you tell me a solution to solve the problem?

How do you see the error is caused by the attempt to access an area of memory dll in bold.

Try to see if your problem has to do with this bug:

I have no idea.
I have posted the link because it could be for you a starting point for further research for a possible workaround.

I tried to change the configuration parameters for tomcat. Specifically, I set "Maximum memory pool to 512MB and the" Thread stack size to 64KB. According to you, this may solve my problem?
