BGP Reset 2130 HA - just one unit

[Eddie in.Mass]

hello folks

we have a TAC open , for couple weeks now (!) for a situation where a HA pair of 2130 running 6.7.0 which has been in use from since Nov 2020-ish , the 2130-1 unit has begun having BGP reset randomly.... we failover to 2130-2 and no BGP resets.

we fail-back to 2130-1 and then BGP resets re-occur.  so frustrating.

managed by FMC , using Security over Connectivity IDS/IPS policy fwiw.

any similar use cases out there ?  thnx

If other one not effecting, i would check the Physical connection and reachability issue with any Peer and Observ the Logs what is the difference.

is both unit peer with same device other side ? different devices ?

check both TCP setting
