 This bug occurs only when v3 hidden services are activated (4 hours after
 activation v3 services). This was my second test of v3 services and this
 issue repeated again. Server was running aprox.150 v3 domains.

 After below warnings, all hidden services stoped working.

 Could be related to #25733.
