Hi All, I've just installed 3.2.2. I'm using a config that was working fine with 3.1 and all seems ok. I get one error that I don't get on 3.1 at startup. kamailio: ERROR: <core> [ppcfg.c:79]: ### added subst expression: /DB/mysql This is repeated for all SUBST statements in the config. I get these errors also: [1293000.484026] INFO: task kamailio:19912 blocked for more than 120 seconds. [1293000.484081] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

I have been getting these errors since 1.x and what I normally do is echo 0 > /proc/sys/kernel/hung_task_timeout_secs to get rid of it. It must be a module that I am loading. Is this possible to debug? I can again get rid of the messages but would love to know whats causing it. BR Shena
