Server stopped after "HikariPool Thread starvation" or "ping between java and wrapper timed out".

Traccar server stopped unexpectedly. Checking the wrapper logs I found this at the very end:

FINEST|2365/0|Service traccar|17-12-05 08:48:06|[HikariPool-1 housekeeper] WARN com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Thread starvation or clock leap detected (housekeeper delta=2m12s509ms653??s528ns).

Never had any issue like this before. Could this be caused by denial of service attack?

Probably it indicates lack of resources somewhere.
