Seems major bug were fixed, but I sitll see the following 
notices and warnings while trunk is under the load

Should the bug be reopened and more BT submitted?

BTW - Sip warning message - WHILE no sip calls in on the 
way - IAX2 transit only!!!!

[Oct 11 09:46:03] WARNING[21882]: chan_sip.c:10962 
func_header_read: This function can only be used on SIP 
channels.

And still some schedule entrys missing
