Day light saving : Prod outage : server shut down / FAILED

If anyone of  you faced the issue of server getting stopped automatically yesterday (Sunday, March 12, 3:00 am), this could be due to Day light saving. Error log as below:

soa_server1.log:####<Mar 12, 2017 3:00:02 AM CDT> <Critical> <Health> <xxxx> 
<soa_server1> <[ACTIVE] ExecuteThread: '35' for queue: 'weblogic.kernel.Default 
(self-tuning)'> <<WLS Kernel>> <> <xxxxssdd:15a91b0a340:-7ffd-0000000018e09e53> 
<zzzzzz> <BEA-310006> <Critical Subsystem JTAMigratableGroup has failed. 
Setting server state to FAILED.

The leasing table won’t be updated with proper time and any gap of more than 1 hour would mark the corresponding server dead. This caused SOA_SERVER1 to shutdown itself.

This symptom is mentioned in  Doc ID 1590774.1.

Solution: Patch 17033308 is available for this issue.
