I have a dedicated server with a few onoin-services on it. One of the services has some traffic to it and this service can't be reached a few times every day, lasting 5-15 minutes.

While it's not available, the other onions is working just fine, it's just this particular .onion (which is the important one).

The service is not of the kind that would get ddos'ed or similar, however, it can have some heavy peaks in traffic, which at some degree correlate with the unavailability. However, no server process is under heavy stress and other services, including other hidden services, is functioning normally)

Server specs:
  {{{
OS: CentOS/RHEL 7
TOR: 0.3.5.8-1.el7

torrc config:

RunAsDaemon 1
DataDirectory /var/lib/tor
TransPort 9040
TransListenAddress 127.0.0.1
DNSPort 127.0.0.1:54
  }}}

A few lines from journalctl output, "xxx" is the onion that can't be reached:

I have not found a similar issue in other tickets and it's very important that I can provide 100% uptime for this .onion.

Many thanks for your time reading this, highly appreciated.
