fbackup(1010): semget failed for the semaphore

I am getting a semaphore error.

Not sure why. I am only using 29?

# ipcs -sp|wc -l
29

semmni 500
semmns 511
semmnu 50

Hi,

I think someone did "kill -9" to your fbackup. When a process was killed by "-9", system has not released the memory of this process. This probably also goes for other memory related resources (e.g. the shared memory segments). I am not exacty sure, but you have to reboot the system in order use fbackup again..

The fabackup was run by accident the other day and it was killed with a kill -9 because it wouldn't respond to any other kill command.

Is rebooting the only way to clear the memory? Can't I use IPCRM to free it? How do I identify which one to remove?

Hi Ray,

Unfortunately, the only way is rebooting the system. May be another way, but I'm sorry I don't know..
