We have run pattern loopback test according to http://kb.digium.com/entry/138 few times for about 3 minutes each. In one test we get 85000 errors and then there where no more errors.
Zttest shows Average: 99,98% but there also comes values like 98%!! once per 10-20 minutes.. Does it mean that our card is crashed? May it be timing error on line? pri debug span 1 shows: [Aug 25 16:20:37] WARNING[2713] chan_zap.c: No D-channels available! Using Primary channel 16 as D-channel anyway!
