I am running a script that connectes to 128 targets and disconnects sequentially from them - in a loop for 100 times Reproducible: Always Steps to Reproduce: 1. Run attached script 2. after disconnecting from 128 sessions, it reconnects again, but fails during disconnection the second time 3. Script hangs 4. tail -f /var/log/messages throws errors attached.
