Beta testing Moosefs network mount for redundancy failover of minecraft server produces crash. /mnt/mfs contains the entire server world. During failover from master to secondary network storage mount the java crash was produced. I am looking for a solution on reducing or preventing the crash if at all possible.

[20:16:02] [Server Watchdog/FATAL]: A single server tick took 60.00 seconds (should be max 0.05)
[20:16:02] [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.
[20:16:02] [Server Watchdog/ERROR]: This crash report has been saved to: /mnt/mfs/./crash-reports/crash-2016-01-17_20.16.02-server.txt
