signal fault in critical section

signal number: 11, signal code: 1, fault address: 0x20c, pc: 0xdfb78e5e, sp: 0xdf605b34

libthread panic: fault in libthread critical section : dumping core (PID: 7000 LWP 4)

stacktrace:

ffffffff

dfb7f8c8

dfb7f674

df9e25c4

df9f09c5

df9eed5a

df9eebb3

df96b7d2

df96b5f2

df92b2db

df92b10e

df92b049

dfb777e4


I am running

java version "1.3.1"

Java(TM) 2 Runtime Environment,
Standard Edition (build 1.3.1-b24)

Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

on Solaris 8 X86.


The application is a server type using RMI to communicate with clients and it also uses JNI to communicate with C++ routines. The error occurs anywhere from a few minutes to several hours after the application has started. The server and client are in loops where they repeat the same sequence over and over again. I have not been able to determine exactly where in the code the error occurs.


Any help would be appreciated.

A signal 11 is a SEGV (memory segmentation error). This occurs when an area of memory becomes corrupted by errant code. Suggest that the fault most likely lies with your C++ code.

Hope that this is of use.
