Description Matthew Farrellee 2008-12-05 21:18:36 UTC 
The QMF Plugins hang on shutdown when they are deleting the ManagementAgent::Singleton.

The current workaround for this is a QMF_DELETE_ON_SHUTDOWN option, which defaults to false.

This is primarily seen on RHEL4 systems.

Reproduce by running the condor_master connected to a qpidd broker:

env _CONDOR_MASTER.DAEMON_LIST=MASTER _CONDOR_MASTER_INSTANCE_LOCK=none _CONDOR_MASTER.DEBUG=D_FULLDEBUG _CONDOR_QMF_DELETE_ON_SHUTDOWN=TRUE QMF_DEBUG_LEVEL=5 _CONDOR_MASTER.PLUGINS=/usr/lib[64?]/condor/plugins/MgmtMasterPlugin-plugin.so _CONDOR_QMF_BROKER=north-15 condor_master -t -f

kill the condor_master, and see:

MgmtMasterPlugin: shutting down...
...deleting ManagementAgent
QMF Agent connection has been lost

Success looks like:

All daemons are gone.  Exiting.
MgmtMasterPlugin: shutting down...
...deleting ManagementAgent
QMF Agent connection has been lost
...deleted ManagementAgent
**** condor_master (condor_MASTER) pid <PID> EXITING WITH STATUS 0

This failure does not happen consistently!
Comment 1 Matthew Farrellee 2008-12-08 19:53:11 UTC 
This appears to be resolved in 7.2.0-0.8 with the qpid-boost fix
Comment 3 Jeff Needle 2008-12-18 13:30:41 UTC 
I wasn't able to reliably reproduce this before, but haven't seen it with recent builds, so moving to VERIFIED.
