Elastic Search gets hanged abruptly

Hi All,

We have a elastic search implemented for our application in Pega 7.3 Environment. But occasionally search gets hanged. I have following error message in the log. Any inputs are highly appreciated.

Full Java thread dump with locks info
"Thread-118" Id=928 in RUNNABLE (running in native)
BlockedCount : 1, BlockedTime : -1, WaitedCount : 0, WaitedTime : -1

ERROR LOG:
