My cluster service shutdow with no reason：
Linux version 3.10.0-1127.10.1.el7.x86_64
ipfs-cluster v0.13.0
Very likely getting shutdown by your system. This seems like the process received a signal to shutdown.
AFAIK, there is no codepath in CRDT mode that would trigger an automatic shutdown without it being the result of handling an external signal (SIGINT, SIGTERM, SIGHUP).
Check your system logs, there might be more info in them.
