Hello,
if it appeared without doing any upgrade to the OS, then likely a
backend/system you interact with has intervals when it doesn't respond
quick enough.
Try to check:
- a database table where you do insert or query is too big (e.g., acc)
- dns server
You can enable latency tracking for actions in cofig, see the core
cookbook wiki, there are some global parameter with 'latency' in name
that should help spotting if there is a particular action in config that
is slow:

If that is not the case, then might be the OS, two days ago or so there
was another discussion here about same topic which proved to be due to a
faulty kernel.
Cheers,
Daniel

Recently encountered a delay issue, packets arrive on system but
Kamailio doesn’t process right away. Here are a few details, any
direction on what I can do to narrow down is appreciated.
The receive queue normally sits at 0 or has random spike, when this
issue occurs receive queue remains high like the below output.
Version 5.1.5
ss -4 -n -l | grep 5060
