The cause could be a misconfiguration of the linux kernel SEMIPHORE settings? What is the output of "ipcs -l"
The suggested settings by IBM are: kernel.sem (SEMMNI) 16384 kernel.sem (SEMMSL) 250 kernel.sem (SEMMNS) 256 000 kernel.sem (SEMOPM) 32 Regard, Uwe -----Ursprüngliche Nachricht----- Von: ADSM: Dist Stor Manager <ADSM-L@VM.MARIST.EDU> Im Auftrag von J.
