[asterisk-users] asterisk crash on DAHDI error: No more room in scheduler

[Allan Oepping]

Ran after problem(problem was over weekend, and this was ran 2 days 
after it started) sorry I forgot about
the -v, I was doing the command at home:

#dahdi_test
Opened pseudo dahdi interface, measuring accuracy...
99.999% 99.996% 99.998% 99.999% 99.998% 99.999% 99.999% 99.999%
--- Results after 8 passes ---
Best: 99.999 -- Worst: 99.996 -- Average: 99.998283, Difference: 99.998286

Asterisk was still running but no traffic was going over the T1's (they 
both should have been filled, or near so)
I restarted Asterisk and traffic came pouring in except for T1 #1 
channels 1-7 and the whole of T1 #2:

*SNIP*

After unplugging T1 #1 (also the timing source) and plugging it back in 
both T1s lit up full with phone calls. Next time I'll try the dahdi restart.

Thanks,
