ASM error Timeout of monitor sequence, no results received

• CA App Synthetic Monitor

Issue/Introduction

From some public station, the ASM monitor is encountering following error.

(1042) Timeout of monitor sequence, no results received

Cause

There was a hotfix applied to public stations. The hotfix should have been without outage, therefore, no customer notification was sent.

Resolution

On some public stations, Cbot agent was restarted/getting killed after the upgrade in GKE clusters because of too tight memory limits. Memory Limits raised (cluster configuration only) and problem was solved after this fix. 
However, stations may have returned timeout errors because of that and trigger customers' alerts
