Hi,
There should be shmget in szin_w-11-2.ALPHA, but what parameters
scripts pass to it, I don't know.
Thanks,

Hi,
The ES40 is running Redhat 6.1, booting from an Intel Linux
Box with 2.2.14, with user space NFS server, that is known to
have problems. The NFS message might come from e.g. the Mail
the program is trying to send out.
The thing that kills the program is the:
> Time = map_shmem: error in shmget: Invalid argument
> test4_a : Error in szin_w-11-2.ALPHA : program crashed, status=1
Is your program doing a shmget?
shmget() itself works on the system, we use it in one of our
applications.
Which is the program causing that error message? I can try to
run it under strace.
Best regards,
Martin Frey
