Subject: Timeout during run transition 
Dear All,

I'm using SL5 and MIDAS rev 4528. Occasionally, when I stop a run in odbedit, 
a timeout would occur: 
[midas.c:9496:rpc_client_call,ERROR] rpc timeout after 121 sec, routine 
= "rc_transition", host = "computerB", connection closed
Error: Unknown error 504 from client 'Frontend' on host computerB

This error seems to be random without any reason or pattern. After this error 
occurs, I cannot start or stop any run. Sometime restarting MIDAS can bring 
the system working again, but sometime not.

Another transition timeout occurs after I change any ODB value using the web 
[midas.c:8291:rpc_client_connect,ERROR] timeout on receive remote computer 
[midas.c:3642:cm_transition,ERROR] cannot connect to client "Frontend" on host 
computerB, port 36255, status 503
Error: Cannot connect to client 'Frontend'

This error is reproducible: start run -> change ODB value within webpage -> 
stop run -> timeout!

Any idea?
