Native code bug with shared memory

Thread view:

I am building a server side java program that calls a C native
library. The C native code allocates shared memory. This code used
to work but now I get:

Unexpected Signal : 11 occurred at PC=0x4C7CB34A
Function=shm_alloc+0x1C6

I believe that signal 11 is a memory violation.

Do I need to request more memory on the command line when I invoke the
java program ? I tried using the -Xss100m switch, but it did not
help.

I am really at a loss to why the native library errors now and worked
fine 9 months ago.

Thanks,

Not much to go on. Any particular operating system? Do you have the C
native library source? Was it tested at any time between 9 months ago
and now? And here's the big one. Did anything change in those 9 months?
