Hi,

We are using ES v 2.3.1 and upgraded our OS to RHEL 7.6  
After upgrade, the ES is not starting due to the following error message-

_2019-03-20 15:42:07,790 - Process is not up after the polling interval 10 seconds._

_2019-03-20 15:42:07,791 - (None, None)_

Can anyone please help me in resolving this error so that ES can start?

I have put some debug statements in es\_master.py, but these are not printed in our application log file.  
Is the debug log from this file being redirected to dev null?

Thanks,  
Harsimran
