Hi there,
We have MQ 5.3 CSD 10 installed on windows 2003 . I experienced the following issue last week with channel reaching its max :

Maximum number of channels reached.

The maximum number of channels that can be in use simultaneously has been reached. The number of permitted channels is a configurable parameter in the queue manager configuration file.

Wait for some of the operating channels to close. Retry the operation when some channels are available.

I am wondering how is the max being reached , when I do display chastatus , I don't see many of them running, also the parameter in the queue manager configuration file has a high value . Can this be caused by threads and processes still running . Will changing the DISCINT attributes help avoiding this type of issue. The thing I am mostly confused about and would appreciate of someone can explain it is :

When a sender channel make connection to a receiver , then I know we should have 2 processes one for sender and one for receiver . Assume this channel goes inactive then goes active again , are we going to have 2 new processes or will it use the same ones . If it uses new processes , then what happened to the old ones , do they still be running.
