It is running in docker, the interval is not stable ~30sec.
I know this is not related to DNS slow queries since I am monitoring them
as well.
I wonder what else can be intermittently blocking ...
I am going to look at the TM locks and the callbacks.
Not many modules used on this one, maybe Dialog module using a DB local
sqlite
modparam("dialog", "db_update_period", 60)
modparam("dialog", "db_mode", 3)

Is this a virtual machine? How often does it happen?
Sometime the VM manager "freezes" the VM for different purposes, like
backup snapshots, ...

I guess action type 16 IF_T is accounting for the entire scope block since
it is recursive.
I wonder why var assignment in the main route scope would do the same :

I am troubleshooting intermittent latency on a
server, several processes
will report slow action at the same time every now and then,
something odd it that some of the actions are most likely not using any
mutexes, I can not imagine how they can end up blocking unless the process
is actually suspended by the OS, however the CPU usage and load average is
quite low on this server.
Is there any reason why assigning to a PKG var could be delayed 3 seconds.
