RPC lock daemon tuning

The rpc.lockd daemon is multithreaded and by default, can create up to 33 threads.

In situations where there is heavy RPC file locking activity, the rpc.lockd daemon might become a bottleneck once it reaches the maximum number of threads. When that maximum value is reached, any subsequent requests have to wait, which might result in other timeouts. You can adjust the number of rpc.lockd threads up to a maximum of 511. The following is an example:

# chsys -s rpc.lockd -a <number of threads> 
# stopsrc -s rpc.lockd
# startsrc -s rpc.lockd
