Hung Process in IOS-XR

So, quick post to help anyone else who runs into this problem in IOS-XR land.

While attempting to issue commands related to the BGP process on the box and I was meet with no response from the box. I was able to break the process with the typical Ctrl + C process, and issue commands to other processes on the box, but the BGP process just refused to response.

Reviewing the logs, I was able to find some errors related to no response being received from the BGP process :

RP/0/RSP0/CPU0:Apr  9 22:55:42.109 : sysdb_shared_nc[382]: %SYSDB-SYSDB-6-TIMEOUT_EDM : EDM request for 'oper/ip-bgp/gl/act/shared/vrf/default/afi/' from 'bgp_show' (jid 65855, node 0/RSP0/CPU0). No response from 'bgp' (jid 1047, node 0/RSP0/CPU0) within the timeout period (100 seconds)

You can see that there is a ‘no response from ‘bgp” string in this log message. The quick and easy way to take care of a hung process like this is to restart it by issuing the following command :

RP/0/RSP0/CPU0: router#process restart 1047 location 0/RSP0/CPU0

WARNING : Issuing this command will rock the BGP process, so plan accordingly. You may experience a brief outage so schedule it during a typical maintenance window.

    • That will certainly do it! This was a pretty interesting one though. Completely sudden and the process showed no signs of problems by issuing various process related troubleshooting commands, either. Really interesting. The only thing that worked was rocking the process.
