Solution ID: P11918
FACT(s) (Environment):
SonicMQ 4.x
Solaris SPARC 8
SYMPTOM(s):
The problem the broker got was "too many open files" because it ran out of (allowed) number of file descriptors.
Especially in reconnection situations the connections are not closed directly when the reference is set to null
A blocking Connection.Close() leads to a deadlock condition
CAUSE:
Reconnecting in case of flow control exception caused an excessive amount of file descriptors.
FIX:
Don't disconnect/reconnect in case of flow control exceptions. Simply keep the connection open in case of a full queue and try to re-send.
