IP Office 12.2 Intermittent Reboots

An issue has been noticed with IP 500v2 systems that were upgraded to r12.2 where the system seems to reboot randomly.

Per the Avaya PCN publication:

Problem description

The IP Office 12.2 systems are facing intermittent restarts after upgrading from 12.1 or 11.1.3.2 releases.
All DevConnect (APIs and SDKs) are not to be considered as they may fail for 12.2.0.0.0 release

Resolution

1. For customers who have downloaded the 12.2.0.0.0 build 50 software, the recommendation is not to upgrade the software
   until further instructions from Avaya to avoid the system restarts. IP Office 12.2.0.0.0 software has been removed from the
   support site.
2. There is no solution or root cause identified at this time; customers who have upgraded to 12.2 release must roll back to the
   previous release until the solution is identified.
