Is this file purged on reboot?
# by default, solaris does a "log rotate" every saturday night (better : sunday dawn) with /var/adm/messages
# it stores and ages the last 6 messages files .
(this is why you find 'messages.0' , '.1' ... until '.6' on /var/adm)
# so you only have the last 6 weeks of log , plus the current one .
# these files are NOT purged on reboot .
good luck , and success !
