Description Lon Hohberger 2006-01-06 20:14:12 UTC

Description of problem:

(this isn't an rgmanager problem, actually - but there's no BZ entry for clumond
yet...)

clumond forks children and waits (currently), 3000ms (3 seconds) for those
applications to complete.  Under many circumstances, it may take >3sec for them
to complete, and it's perfectly reasonable to kill them if we're on a time
schedule.  It is probably better, however, to kill them with SIGINT or SIGTERM
prior to sending them SIGKILL so they have a chance to clean up.

One particular instance where this has become a problem is when using clustat: 
clustat opens a connection descriptor to ccsd, which is persistent until closed.
 If clustat is taking to long to complete (which is often), a ccsd connection
descriptor is leaked.  If ccsd runs out of connection descriptors, nothing will
be able to configure/reconfigure, and this message will appear in the logs:

"Error while processing connect: Resource temporarily unavailable"

Server shouldn't misbehave no matter what client does, so this is a ccsd's bug,
too. 
CC jbrassow

Clumond should be a good resident and issue SIGINT or SIGTERM before SIGKILL;
will fix.

Comment 2 Stanko Kupcevic 2006-10-03 17:52:41 UTC

Since server side has been fixed, this issue is a non-issue any more.
