Hi all,<br>
<br>
After running fine for a few months now asterisk seems to hang<br>
frequently , still functioning but the DAHDI channels seem busy (users<br>
report a busy signal when calling or being called)<br>
<br>
A reboot will allow it to run for another day or maybe 2 or 3 till the<br>
problem occurs again.<br>
<br>
<br>
running stock Asterisk 1.6.2.9-2+squeeze2 on Debian with stock kernel<br>
2.6.32-5-686<br>
<br>
i get the following errors:<br>
pri_dchannel: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2<br>
<br></blockquote><div> Your telco provider has crc on or off , that is not matching with your server cross check with them. <br>and this problem solve 4 problems <br></div><div> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
(happens on all 4 spans)<br>
<br>
and the following in dmesg:<br>
[ 9004.635323] NOTICE-xpd_bri: XBUS-00/XPD-01: D-Chan RX DROP: BADFCS: 252<br>
[ 9004.635332] NOTICE-xpd_bri: XBUS-00/XPD-01: D-Chan RX: current<br>
packet[0..2]: 55 55 FC<br>
[ 9004.635340] NOTICE-xpd_bri: XBUS-00/XPD-01: Multibyte Drop: errno=-71<br>
<br>
<br>
Channel 0/1, span 1 got hangup, cause 18<br>
<br>
According to my searching on the web the last two weeks i understand<br>
that the first mentioned error can indicate a wrong configuration<br>
setting or buggy hardware.<br>
<br>
Have tried many options but the dahdi config as copied over from the<br>
same machine (with elastix 1.4) seems the only one that seem to work<br>
<br>
anybody has a clue?<br>
much appreciated<br>
