Summary: [patch] sip peer qualified failed, asterisk lock.
Description:
We just had asterisk lock on us tonight. Best we can guess is because we
lost our SIP PEER (via qualify).
See output from 'show core locks'.

Maby it is a deeper problem and it has to do with the kernel tcp stack and
synflood protection.
when a qualify fails it migt retry to connect and the kernel might see
this as somekind of synflood attack?
so the kernel might be blocking the asterisk from flooding?
and asterisk locks up whit waiting connections?
