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.
