Nexus 5k Error: Too many files open in system

[c234]

I have been trying to debug my Cisco Nexus 5K Switch but haven’t gotten anywhere. The issue is that there are too many “vsh sessions” that are open. I have tried using the “kill” command to close them but whenever I run ANY command on my switch I receive an “Error: Too many files open in system”or “Error: Internal: library libppmcli.so could not be opened ….” or “mts_get_proc_name: Couldn’t open /proc/17738/cmdline, error 23”. Rebooting the switch is a last resort because we required 24/7 uptime on the switch. Any help is appreciated.

did you find this document about vsh session locks ?
Cisco Nexus 9000 Series NX-OS System Management Configuration Guide, Release 10.2(x) - Terminal Lock for VSH Sessions [Cisco Nexus 9000 Series Switches] - Cisco

If you are required 24x7 uptime, you will have a redundant switch pair do you ?
-> reboot only one at a time

Hello,

maybe it is possible to identify the process that is causing this using the command:

show processes

and then kill the process:

kill <PID>

Also, can you post the output of:

show system internal mts buffers
