repeated CANCEL requests, to which Asterisk does not react. A bit later,
Asterisk sends 183 Session Progress and 486 Busy Here/503 Service
Unavailable, to which it gets no answer, retransmits and locks up.
There is also a warning "chan_sip.c: Unable to cancel schedule ID xxxxx. 
This is probably a bug (chan_sip.c: send_response, line 3997)." in both
cases.

It seems that when the lockup occurs, "sip show channels" and "sip show
peers" work fine, but "sip reload" and "module reload" return immediately
without any output or anything happening.

I also checked the logs from before the upgrade to 1.6.2.0-rc2 and we have
had the "Maximum retries exceeded on transmission" warnings on both 1.6.1.1
and 1.6.1.6 without chan_sip locking. The "Unable to cancel schedule"
warnings appeared after upgrade to 1.6.2.0.
