Hello Team,

   Just few hours ago we have upgraded our pa 1410 panos from ver 11.1.10-h1 to 11.1.12 recommended by tac to solve error log "devsrsr: virtual memory limit exceeded, restarting ".

Now through these few hours after apparently a successful upgrade we are receiving many new error log.

eventid: tls-X509-validation-failed

object: 

fmt: 0

id: 0

module: general

severity: high

opaque: MLAV Server certificate validation failed. Dest Addr: ml.service.paloaltonetworks.com, Reason: certificate has expired

----

What is this about and what action you recommend?

TIA

MR
