Webhook service stuck

[eugenyuk]

Hi guys,

I use webhook 2.8.0 on my Ubuntu 24.04.3 server. Every half hour a request is sent to Webhook and the latter runs the signal-cli shell command.
Yesterday it stuck for unclear reason. At 01:00 there was the last successfully handled request. The next one (at 01:30) and several consequent requests were not handled at once but queued and handled at 06:49 (the time when I logged in to server to check what happened).
The webhook script is run as: webhook -ip localhost -hooks webhook/hooks.json -verbose in side my screen session.
This is the log:

I've noticed the strange ^ character in the log when the service stuck at 01:30:03 and second ^ when it back to work at 06:49:56.
The whole log I attach. Could you please help me to understand the reason of the issue?
Thank you.
