Yes, I checked the log and the messages are: 2017-08-22 21:43:42.287 Info: TaskServer: profiling-task.xqy [4136613570697343302]: Starting, start: 32361, group size: 10, outdir="/profiling/trial-058/group-3237/ 2017-08-22 21:43:42.287 Info: TaskServer: " 2017-08-22 21:43:42.405 Info: Saving /marklogic/Forests/Meters/00000a02 2017-08-22 21:44:34.572 Notice: Starting MarkLogic Server 8.0-3.2 x86_64 in /opt/MarkLogic with data in /marklogic 2017-08-22 21:44:34.617 Info: Host **** running Linux 3.10.0-327.18.2.el7.x86_64 (Red Hat Enterprise Linux Server release 6.8 (Santiago)) 2017-08-22 21:44:34.690 Info: SSL FIPS mode has been enabled
The first message is from my task indicating that the 3237st (out of 50,000 in the queue) is starting. Then the MarkLogic start message for no obvious reason. It’s not a time at which a scheduled server restart would have likely happened and nobody was (or should have been) awake at that hour and I’m the only person who should be doing anything with this server anyway. What’s interesting is that I’m getting this restart consistently at about the 3200th task, so it feels like either a time out or a resource exhaustion that then triggers a restart, but there are no messages about any kind of failure, out of memory condition, etc. I’m pretty sure it’s an issue with the configuration of the underlying linux server but I wanted to know if there were any conditions under which the Task Server or ML server itself would spontaneously restart.

I'd look elsewhere for an error. Specifically, I'd check ErrorLog.txt, find the time when a restart happened, and look to see if anything interesting was logged just before.
