sometime /var/adm/messages size 0

Hi experts,

sometimes i notice in my Solaris 9 /var/adm/messages size 0.

It continues for 1/2 days then again /var/adm/messages is start filling up with logs!!!

What could be reason behind it. and if its a problem what could be the solution.

the logfiles are rotated automaticly. have a look at "logadm".
