Hi, first of all many thanks to your great programs.
We have been running a single pritunl server (now v1.30.3116.68) on ubuntu 20.04.3 machine, where dozens of clients can connect, with multiple device feature enabled.
The pritunl server suddenly denied all multiple-device connection of any user, including newly-created one, making an error
"unable to assign ip address, pool full". When there is no connection from a user (so the web UI says offline) it accepted one connection but not more.
This is the snippet of the log, which denies the second connection of a user:
[winter-thunder-9503][2022-04-20 14:23:27,699][ERROR] Unable to assign ip address, pool full server_id = "6225cbdbbfbdafd4c3915****" instance_id = "6231a364b965eac1ab09****" user_id = "62341bf5b965eac1ab0a***" multi_device = true replica_count = 1 network = "10.8.0.0/24" user_count = 22
There seems to be no mongodb issue (from the mongod.service and mongodb log I can tell).
After I re-started the pritunl server via web UI, the symptom was gone and started to work well.
What can be the source of the problem and how should I avoid this?
