Process limit was never exceeded .We have monitored number of process created on OS . The number of process never exceeded the max process limit . Max process limit set on Operating system is 4096 ( nproc kernel parameter is set to 4096 as mentioned quick beginnings guide. If some one has experienced this kind of problem on MQ 7 , can you please share your experiece .
Server is doing fairly good . Number of process created by MQM are in control. Process limit never exceeded max process configured on the server . CPU , Memory utilization are OK
It was found increase in client connections through server connection channels has created many amqzlaa0 process resulted in Process limit exceeded error . Currently we have restricted the client connection by setting MAXINST property of server connection channels. Thanks for your help .
