DB2 FOR LUW / DB2FORLUW / 950 - DB2

In DPF environments, the release of FCM buffers or channels may 
take longer than expected if a large number of FCM resources are 
allocated. One possible consequence of this is 
db2stop may time out due to it taking a relatively long time to 
free fast communication manager resources. FCM is shut down 
during the final phase of db2stop. When this phase takes longer 
than the time specified by START_STOP_TIME then the node is 
forcefully terminated. Another possible consequence is 
performance slowdowns that coincide with periods when FCM 
 
automatic tuning releases resources.

If db2stop is timing out then increase the START_STOP_TIME value 
in the database manager configuration.
