I tried running debug=3 on the other server with the following command
but I suspect it generated too much load because the server got
unresponsive after a while and I had to turn off the debug:
"kamcmd cfg.set_now_int core debug 3"
I searched calls on the time window when the "dlg_clean_run(): dialog
in early state is too old" -messages were appearing in the log, and
noticed some calls that were on the early stage quite some time. The
early stage lasted about 40seconds. Could this trigger the alarms and
is there any way to adjust the timers if that is the case here? The
target is a PSTN gateway so its quite normal that sometimes there is a
longer period of time when we try to reach the B party. Also it would
be nice to confirm this via the proposed debug logging, but with less
impact generally on the server calls. Maby there is a way to just
debug the dialog module itself and not the whole core ?
Cheers,
Olli Attila
