Re: [GENERAL] Lock problem on Solaris
Tom, Thanks. Running ipcclean fixed it right away.

(You probably will need to zap the old shared-memory segments as well as the old semaphores; these tools will handle both tasks.) Our distribution includes a shell script "ipcclean" that purports to do this for you, but I wouldn't trust it too far, since the output format of ipcs is somewhat platform-specific. regards, tom lane
[GENERAL] Lock problem on Solaris
When I start postmaster, I get the following: IpcSemaphoreCreate: semget failed (No space left on device) key = ... I know that this is caused by not having enough semaphores and can be fixed by increasing some settings. However, it normall works fine with the setting, and a nasty crash killed it this morning. I think that for some reason, some semaphores are still being held. I have ps -aux'd and killed all the postgresql processes, and have erased all my files in the /tmp directory. What else can I do?
