Description:Suddenly, the extensions stop responding to keyboard events, even they are receiving calls and giving tone.

i have been receiving these three messages each time before it happens, the messages are random.


i got TE410P, the oinly way to fix it is to rmmod and modprobe again the module wct4xxp

I've also discovered that when it happens, the PRI gives busy tone

By: gavin (gavin) 2003-09-04 03:12:42

I am having a similar error.  
Can you trigger this behavior by running "rpm -qa"?

See thread:
Re: [Asterisk-Users] TE410P - one way audio, after 'rpm -qa' on RedHat 9

By: asker (asker) 2003-09-05 16:05:41

well, i've change the card from the PCI port it was using and it gets worst.... i think i had it in the last PCI slot, now one before... i'll try to get it to the first slot as soon as i can.

Please i need to fix this before i start getting serious problems.

Reminder sent to markster, martinp

see the last bugnote, please

By: x martinp (martinp) 2003-09-05 16:38:34

OK, so you're using some channels for HDLC and some for voice. If you call in and execute

exten => _X.,1,Answer
exten => _X.,2,Echo

Can you hear yourself ? I want to check if the streams are being passed both ways.
Also what do you mean "suddenly stops working" ? It's working for some time and then stops detecting DTMFS ? How recent your asterisk/zaptel/libpri code is ? Can you also post some "pri debug span <span_no>" ? And the last thing, did you test it when you don't use HDLC channels ?

By: asker (asker) 2003-09-09 09:04:42

martin, the thing is I'm not using any HDLC, not that i know.... so i didn't understand your question, sorry.

By: asker (asker) 2003-09-09 09:09:53

i've updated my zaptel.conf so you can check it... i tested the answer and echo and i can hear me normally...

CVS is from septemper the first, and about suddenly stops working is true, it is working, everyone is talking, and then without aparently reason.... it stops detecting DTMF and the PRI lines start giving busy tone.

By: asker (asker) 2003-09-09 09:14:12

how can i save the pri debug span 1?

By: x martinp (martinp) 2003-09-09 10:23:59

asterisk -vvvcng | tee /root/log

then type "pri debug span <span_no>"

after you get the log type "stop now" and send the log

By: x martinp (martinp) 2003-09-09 10:25:01

Also can you try that:

modprobe wct4xxp
rpm -qa
start asterisk and see if you now have the problem ....

By: asker (asker) 2003-09-09 21:02:49

looks like i had it, and could not get asterisk to work a bit after that.....

By: asker (asker) 2003-09-09 21:22:48

in fact after that PRI didn't work again, i guess i'll have to go to the site ASAP

By: asker (asker) 2003-09-09 23:10:45

OK, i just came back from the site where the server is located.

It seems that form a fresh start and doing modprobe wct4xxp and then rpm -qa

this turned off the card, and by off i mean off like if no voltage coming in!

i had to halt the server, power it off and then restart it again so the card came back to life.

Something tells me you're on the way to correct this.. maybe? i'll keep the hope, do i need a new CVS?

By: x martinp (martinp) 2003-09-10 09:59:24

Did you try to "rmmod wct4xxp; modprobe wct4xxp" after that ? It did help on the other system. But that's temporary 'solution'

By: asker (asker) 2003-09-10 20:18:47

martin, usually is that what i do, in fact i made a script that stops asterisk, do rmmod, kill al mpg123 and finally... modprobe again and start asterisk.. but las night the card run out of energy, no led was lighting and not even rebooting the machine brought it to life, until i manually turn off the machine, unplugged power cord and the connect and start again.. whe i replugged power cord, card came back to life

By: gavin (gavin) 2003-09-11 12:58:08

asker> card run out of energy, no led was lighting and not even rebooting the machine brought it to life

I have had this problem also.  After loading and un-loading the TE410P modual many times due to one way audio.  Could be a big problem if you do not have easy physical access to the machine.

By: asker (asker) 2003-09-22 08:39:25

hello, i wanted to know if there is any advance on this issue....

it keeps happening, even it has been less common than before. Yesterday i've applied a CVS so i'll ee what happens.

By: asker (asker) 2003-09-28 12:48:40

Martin, Mark i was just sitting in front of my * box, installing the new CVS from today, when i picked up the phone, heard a click and saw this in the CLI:

RI: Read on 101 failed: Unknown error 500
PRI got event: 7

and then, the extension stop to receive the tones.

I gues i can't be more specific! PLEASE HELP ME!

By: asker (asker) 2003-10-09 18:19:10

Now i got something more real..

I happen to establish 2 exact times of a fall of asterisk, check messages file and found that the last event in both fails was the same....

Oct  9 07:39:55 WARNING[1293196592]: File chan_zap.c, Line 3313 (zt_read): zt_rec: Unknown error 500

that was the one, i hope this help.

Even more, i've found a kind of way to reproduce it... if i get X up, the falls start happenning very often.

Thanks in advance.

well dont run X on your * server! :P  Sounds like an IRQ issue.  Move the card to a diffrent slot.

By: John Todd (jtodd) 2003-10-19 20:09:17

While I believe that Asterisk should not be failing with the error types you are discussing, I will also concur and say that you should not be running X on an Asterisk system, or anything else that produces a large number of interrupts.  

If you do not run X on your system, are you able to reproduce the symptoms you describe?

Additionally, have you tried running your card and configuration on a different motherboard?

Still a problem asker?

By: Brian West (bkw918) 2003-12-14 11:47:24.000-0600

Seems to be a local issue.  Running X on an asterisk system isn't a good idea.  Zap hardware is interrupt hungry and X adds more overhead and problems could arise.
