I have just finished installing a new asterisk box at my work. The box is quite hefty, dual Zeon 2.8s with SCSI drives and 2Gb of memory. I have a 4 port Digium T1 card for channel bank and PRI access.
I activated a PRI from a local CLEC (DMS-500 based, National protocol). This PRI is on slot 2 of the card and is set as the primary timing source. It is ESF/B8ZS. All the software is latest CVS HEAD as of 5/22/04. My problem lies in random intermittent drops of calls. The entire PRI seems to disappear, dropping all current established calls. I see occasional printouts on an asterisk management console showing all 23 B channels resetting with no reason given: pbx1*CLI> -- B-channel 1 successfully restarted on span 2 -- B-channel 2 successfully restarted on span 2 -- B-channel 3 successfully restarted on span 2 -- B-channel 4 successfully restarted on span 2 -- B-channel 5 successfully restarted on span 2 -- B-channel 6 successfully restarted on span 2 -- B-channel 7 successfully restarted on span 2 -- B-channel 8 successfully restarted on span 2 -- B-channel 9 successfully restarted on span 2 -- B-channel 10 successfully restarted on span 2 -- B-channel 11 successfully restarted on span 2 -- B-channel 12 successfully restarted on span 2 -- B-channel 13 successfully restarted on span 2 -- B-channel 14 successfully restarted on span 2 -- B-channel 15 successfully restarted on span 2 -- B-channel 16 successfully restarted on span 2 -- B-channel 17 successfully restarted on span 2 -- B-channel 18 successfully restarted on span 2 -- B-channel 19 successfully restarted on span 2 -- B-channel 20 successfully restarted on span 2 -- B-channel 21 successfully restarted on span 2 -- B-channel 22 successfully restarted on span 2 -- B-channel 23 successfully restarted on span 2 pbx1*CLI> (This is from an asterisk console started with -rvvvv.) Has anyone encountered similar behavior in the past? If so, what was the resolution?
