I'm wondering if anyone else has experienced this. After the upgrade we're getting this error in the syslog file:

Jul 12 10:40:36 es2 systemd[1]: elasticsearch.service: main process exited, code=exited, status=1/FAILURE
Jul 12 10:40:36 es2 systemd[1]: Unit elasticsearch.service entered failed state.
I've seen the same mbeans Java error on other posts but everything I've tried to get the service started fails. The main thing I've tried is tweaking and checking permissions of the user that runs the elasticsearch service...in my case it is "esearch." Also tried running it from the command line with no luck.
I've also got a request for help on GitHub here: https://github.com/elastic/elasticsearch/issues/25691
Thanks in advance for any help that you could give us with this issue.
