asterisk users - Feb 2005 - Asterisk-HEAD more stable than Asterisk-1.0.5

hi everyone,

just a poll toknow if someone out there is using intensively 
asterisk-HEAD version (mean the very last version
of asterisk).
I currently used asterisk.1.0.5 and sometimes I need to kill the process 
because it's freezing (deadlock maybe, or something else...).
is this kind of problem occurs to someone else?
is this problem disapears with the HEAD version?

Thanks

Florian
