I'll keep this short and I hope its just a misunderstanding of java on my part. All my Elasticsearch nodes are reporting a JVM uptime between 1 and 25 hours. The strange part is all the JAVA process have a start date of 9+ days. How can the JVM uptime be less than the JAVA process time? I see nothing in the Elasticsearch logs with any indication of the issue. Thanks for your help. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

At a guess, it might mean the actual time it spent processing, as opposed to service runtime.

I was thinking the same thing, except every ~25 hours the jvm uptime resets back to zero, but the java pid and start time remain unchanged.
