berkely  checkpointing and matlab are working from the command line for me.

However when I try to use it with SGE I get a "restart error".

Here is what I sent to the berkeley checkpoint people:

(I also get the relocation error from the command line)
   manage to checkpoint matlab processes  from the command line.
But when I want to use SGE I get the error:
/lib64/libc.so.6: relocation error: /lib64/tls/libpthread.so.0: symbol
errno, version GLIBC_PRIVATE not defined in file libc.so.6 with link time
Restart failed: No such device or address

The relocation error I get on the start using cr_run.
The Restart failed I get when trying to restart.

I start matlab thus:
${BLCR_HOME}/bin/cr_run env LD_PRELOAD=libcr.so.0:libpthread.so.0 matlab
-nojvm -nodisplay -nosplash < $H/test.m

and try to restart thus:
${BLCR_HOME}/bin/cr_restart $ckptfile

my log file says this:
Jan  2 14:24:36 kam02 kernel: Skipping a socket.
Jan  2 14:24:36 kam02 kernel: Skipping a socket.

Please help.
