I have problem with asterisk 18.104.22.168 and dahdi 22.214.171.124 - time to time it “freeze” - in log file there is information:
[Dec 22 14:38:43] ERROR chan_dahdi.c: PRI Span: 5 Trying to queue MDL-ERROR (F) when MDL-ERROR (F) is already scheduled
asterisk is working, but when i try to execute “core show channels” it shows only header of information:
Connected to Asterisk 126.96.36.199 currently running on ZDAP (pid = 19506)
ZDAPCLI> core show channels
Channel Location State Application(Data)
ZDAPCLI> core stop now
asterisk also do not respond to “core stop now” - only “killall -9 asterisk” can stop it. What could be a problem?
