That cpu spiking is another issue separate from the stability issue (I think). Not sure where the discussion of the spiking ended up a few weeks ago, do you remember? I've not tried to dig through the code, but it wouldn't surprise me if some temp code exists that might be polling the tdm card (or something like that) as an aid towards identifying the stability issue. Gut feeling suggests that if stability is truly related to tdm design problems (or whatever), then resolving that issue probably should be a precursor to chasing the cpu spikes. Any thoughts? _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
