Trouble Starting Monitor Daemon

[Craig Weldy]

I am running CL 5.7 on a linux VM box.  I took over support of this system over a year ago.  It has two test sites on it.  I am looking to make a second copy of the sites and I did so  The two original test sites are running.   I started the Lock manager for one of the new sites, with no problems, but when I try to start the Monitor Daemon through the site Daemons gui tab or through the command line, I don’t get any errors but the Monitor Daemon dosn’t start up.  In the network monitor all the threads are “RED and DEAD”.  When I go to the Site Daemons Tab and tell it to Kill all daemons I get this message:

Lock manager terminated.

[0:TEST] oilSysSemOpen: semget failed

Sem Name = /hci/qdx5.7/integrator/bcn_emrtest15/NetConfig Key Generated : 704783539

[0:TEST] msiGlobalInit: Can’t open guard sem: No space left on device

msiGlobalInit: NetConfig = /hci/qdx5.7/integrator/bcn_emrtest15/NetConfig

Lockmgr    is NOT running

hcimonitord is NOT running

Unable to initialize MSI, err = -1

I checked the disk space due to the “No space left on device” line and there is plenty of space on all partitions (none more than 30% used.  I suspect I am just missing something, but at this point this is a mystery!

Hi Craig,

It looks like you’re not out of disk space, but out of semaphores. We are on HP-UX and have run into that problem also when trying to add another process: it just won’t start if it can’t get a semaphore. At that time it looked like a lot of semaphores were unused/’ghosts’ (not sure what the correct term is) after we deleted semaphore-files in the $HCISITEDIR/exec directory. So never do that!

To clean up semaphores I think you will need a reboot. I am not aware there is a way to clear unused semaphores, so if someone knows this, please let us know.

You should also have a look at kernel parameters for semaphores: you may have to increase the maximum number of semaphores.

We check the number of semaphores with

Code:

ipcs -s|wc -l

Hope this helps.

Robert,

    Thanks for the reply and you hit the problem right on the head.  I passed the info to one of my SA’s and he had it reset in no time flat.

    Thanks for the help.
