[SR-Users] Redis error: Server closed the connection / nbd_redis / kamailio 5.3.5

[Daniel-Constantin Mierla]

Hello,

based on these details, you can do 'kamctl ps' to see the type of the
process printing the disconnect log message matching the pid. Maybe is
some process with low activity, not using the redis connection that much.

Cheers,
Daniel
