I got the following error message when running the "last" command at
my Solaris 10 server :

# last
/var/adm/wtmpx: Value too large for defined data type

Looks like my "wtmpx" file has reached its size limit :

# ls -lt wtmpx
-rw-r--r-- 1 adm adm 2150910511 May 12 19:15 wtmpx

Can one reduce the size of wtmpx ? If yes, how ? I would like to at
least get some information out of the wtmpx file before I zero it out
and find ways to prevent it from reaching this big in future.
