Hi Shawn, re: > I just had version 5.11.1 installed on my LINUX machine and updated my > .cshrc file accordingly. However, any time I try to run a GEMPAK program > now, I get the following error: > > semget: No such file or directory > semop: Invalid argument > [GPLT -1] The requested IPC message queue is locked. Hmm... This is the first report we have had of a problem like this. > The IT guy in our department has no clue, and I've also tried sourcing back > to the old version of gempak (5.7.4), which strangely gives me the same > error (it previously worked fine on the same computer). Do you have any > insight as to how I could fix this problem? Any help would be appreciated. I would try a reboot. The fact that the older version of GEMPAK failed in the same way that the new one does seems to indicate that the problem is system-related, not GEMPAK based. > Thanks very much, Please let us know if a reboot fixes the problem you are experiencing.
