SIGSEGV error occurred during init a JDOM element

992496 Newbie
Currently Being Moderated
HI!

I have faced a problem related to segmentation failed in Linux box. I got following error -

J org.jdom.Element.<init>(Ljava/lang/String;)V
...
siginfo:si_signo=SIGSEGV: si_errno=0, si_code=2 (SEGV_ACCERR), si_addr=0x00002aab2ac30000

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

It is also shows in the log that 100% use of PermGen space. Why this segmentation fault occurred? Is it related to JDK or JDOM?

In my understanding, problem is related to JDK and occurred due to 100% use of PermGen space. But I am not sure as Problematic frame is J.

Another interesting point is "error occurred during error reporting (printing native stack), id 0xb".

I am using JDK6up20 and Linux environment. Please find logs below.

    Your system have memory restrictions to reserve more memory to perm gen ?

    Thank you, Claudio.

    So, New Object construction required memory allocation and the problem occurred due to native call by JVM during memory allocation. If that is the reason then why not the problematic frame is 'C' or 'VM'?

    I am little bit curious about- how memory allocated in PermGen space? Is this a same way as heap (grows incrementally upto certain limit)?

    Permgen often causes "java.lang.OutOfMemoryError: PermGen space" that is not the reported error and is not the definite issue you are facing.

    I suggest to have more memory allocated to permgen because it reached 100%, as you pointed out. Tune one parameter and compare their results.

    Also, try to use OpenJDK as it is compiled with debug enabled and you are going to see a better stacktraces for the java frames.

    PermGen space stores class structures and class metadata, it doesn't grow much while the program is running, it allocated memory when classes are loaded by classloaders. Also, programs that performs bytecode instrumentation (hibernate, spring, jboss seam, etc.) requires more permgen space than other programs as it modifies class structures.
