[GE users] Problem with FineTurbo Paraallel Job running

Hi John / All,


I too face the same problem.

By giving ipcs it shows many Shared memory segments and Semaphore
Arrays.

How can I clear the below:

For instance


------ Shared Memory Segments --------
key        shmid      owner      perms      bytes      nattch     status
0x00000001 131072     root      600        655360     2
0x00000000 196609     root      600        393216     2          dest
0x00000000 229378     root      600        196608     2          dest
0x00000000 262147     root      600        393216     2          dest
0x00000000 294916     root      600        196608     2          dest
0x00000000 327685     root      600        393216     2          dest

After running cleanipcs, did you run ipcs to check that the shared
memory segments really had been removed?
cleanipcs removes shared memory segments (etc.) belonging to a given
userid. You might have to call it as the particular userid which owns
tose shared memory segments left behind.
