It's generally a good idea to set outConScanPeriod to be smaller than
inConScanPeriod so that clients usually close connections. When servers
close connections, clients can end up having to retry calls due to the
connection closures.

What is the setting of threadPerConnectionPolicy ?   How many concurrent
calls do you have relative to the setting of 200 for the thread pool size?

What happens when the processes become "blocked"?  Do they recover after
a while, or stay blocked for ever?  If they're blocked forever, try
attaching with a debugger and get a stack trace for all the threads.

If it's only temporary, you can get more information by running both
ends with traceLevel 25 traceThreadId 1 traceTime 1. That will output a
lot of debugging information that will hopefully show where the hold-up
is.

Cheers,

Duncan.
