asterisk users - Jan 2005 - Asterisk/Sip crash "Failed to grab lock"

Hi,

Since around a week i have one asterisk server how stop responding randomely.
CVS HEAD with RealTime engine used.

The debug log only write "Failed to grab lock, trying again..." until
i
stop Asterisk.
No more activity for IAX or SIP channels (no log...). CLI still responding.
When i try to stop asterisk (stop now or crtl+C) nothing happen and cli die 
but asterisk still running.
This problem appear around each day.

I have notice also many new warning :
DEBUG[1608]: Avoiding initial deadlock for 'SIP/1.1.1.1-081f28b8'
WARNING[1608]: Avoided initial deadlock for 'SIP/1.1.1.1-081f28b8', 10
retries!
1.1.1.1 = another *

Seems change in SIP channels make theses new warning.
No deadlock channels or problem like this with cvs from mid-december.

Any idea ?
