Problem: Both inbound and outbound messaging queue counts were increased, however, performance degraded as a result.
Description: After increasing inbound and outbound message queue count, the default maxThreads of IIOP socket listener is insufficient.
Solution: Increase the maxThreads of IIOP socket listener by editing the <hostname>_iiop1.properties file, and restart Unwired Server. The maxThread of IIOP socket listener must be larger than the sum of all nodes needed IIOP thread counts.
