Just correct me @Vinayak_Sapre my total RAM capacity is 64 GB and in that i have assigned 32 GB. last 6 month my service is running with same setting and it happens suddenly.

Ganesh,
Other processes running on this specific machines were taking up 31358668 (~30GB) at the time of ES start. You cannot compare with other nodes or past history of this node.

If you are still seeing the issue, "top" command with sort on memory (shift+m) will give you processes consuming most memory.

when i check with TOP command and im getting below output,

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
24990 root      20   0   30.8g  29.3g 166360 S   0.0 46.7  33:20.74 rsyslogd

Ganesh,
I don't know much about rsyslogd debugging. But that process is your issue.
