Hi list, I'm getting an error on a E1 link to the telco, after some weeks of operation without trouble.
I have an asterisk with a TE405 in passtrough mode: two E1 are connected to the Telco, two E1 are connected to 2 Siemens PaBX. Only 15 channels are used on each E1 (conf is attached).The system has been in production for nearly a year, and does work flawlessly for weeks, then I mysteriously get errors on the first PRI span, which is used as primary clocking source. It happened again this Sunday (while the system wasidle), after six weeks of operation without trouble. Call are dropped, and users are angry. It has happened 4-5 times during one year. Reloading zaptel modules and restarting asterisk does bring the system back to normal.
As far as I can tell, pri debug span 1 shows nothing special (see attached log). The Telco says that there is "drift in the synchronization". System load as shown by top is very low, vmstat shows no CPU spikes, TE405P has its on interrupt. I already changed the TE405P. I have other similar systems running without any trouble, so any idea about improving this installation would be welcome. I can provide moreinfo if needed. Main differences with my other similar installations are: two E1 are used, and system is 64 bit (Asus MB with Opteron).
