We are writing automated tests that involve repeated connects and disconnects with test sessions. Two connects/disconnects without delay work fine, but the third connect fails.
With delay 1 second only one connection work, the second failed.
2 files attached with logs, connectionError.log.tgz is without delay and ..._sleep1s... with a delay of 1 second between tries.
