Hello. “show tech” takes more than 24 hours to run. The issue is observed on two switches. Initially one of them had EOS 4.15.5M and the other 4.15.6M. Upgraded both to 4.20.11.M-2G. The issue still persist. Any suggestions?

Hi Boris,

The “show tech” runs several platform commands so there could be an interaction occurring that is hosing up the ConfigAgent. I saw a previous case where a customer was polling the switch at the platform-level which slowed down their CLI. Or it could be something as simple as the filesystem being full, possibly something was crashing which was filling up your schedule tech support files and they subsequently filled up your flash causing issues on login and other problems. But in truth, without more information, there is no way to know.

Can you check the following:

#show agent logs crash ==> see if there is an agent constantly crashing and could just be restarted to fix (or had been)
#bash dmesg
#bash sudo du -ah /var/log | grep -v “/$” | sort -rh
#bash sudo ls -lahRS /var/log
#bash sudo df -i
#sudo lsof | grep -i deleted

The above is to check and see if this is just of matter of cleaning up full filesystems.

Please call up TAC and get a live engineer to take a quick look. They’ll confirm platform (show version), see if anything is in the logs (show log system), check the agents, size of the files, etc. and be able to narrow it down faster than my guessing.
