RE: [FLASH-USERS] FW: 3D RM Problem

Hi Mike:

Thanks for your quick hint. However, when I type in

"gdb -c core", it gives me:

"/teal/caip3/zhang/FLASH2.1/setups/rm_3d/core" is not a
core dump: File format not recognized

Although it says in stderr there is a core dumped. Any
suggestions? As a reminder, our machine has a LSF queueing
system and "uname" gives:

SunOS teal.rutgers.edu 5.7 Generic_106541-23 sun4u sparc SUNW,
Ultra-Enterprise-10000

Best

Shuang, according to your stderr log, you are getting a core dump from one
of the processors -- have you tried looking at a stack trace from the core
file to see where it is crashing? It is not clear what the problem is
from the files you've attached, but it is possible that some error
messages are buffered and not being properly written out when that
processor crashes.
