We have windows service using c# that uses RFA8_NET120_x64 (184.108.40.206). On some random days, session.Acquire("sessionName") call fails. We have 4-5 retry mechanism in place when acquiring session with a certain time interval in-between and all try attempt fails.
Most of the time, service restart works fine. So it doesnt look like code / config issue. Also same code + configs works fine on another machine.
Its not machine specific issue as well since we observed this failure on both machines randomly.
We can not enable logging on production servers but seems when trace logs are enabled - it starts generating log file only when we actually try to login - and this login call happens after session.Acquire() call.
We have try..catch around Acquire() call and can see below in our service log file when Acquire() call fails..
ErrorType : 1
ClassificationType : 4
SeverityType : 1
What else we can do to see what exactly is wrong when session.Acquire() fails?
