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!
