Re: uid and gid for /etc/password changed. var 100%
First look for /var 100% issue. Find out the files that are occupying huge space.
# du -kx /var/* | sort -rn | head -n 20 <== will list top 20 big file
Unnecessary can be backed up in some other place.
log files can be trimmed.
Crash file can be removed.
Hope this helps.
Regds,
R.K.

Just go through following threads and you will find a lot of things here to get free space out of /var.

Dear,
Please check this link for 100% of /var
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1112992
check for any process that fills the /var file system,
Use top to check the current CPU utilization and kill if any unwanted process is there.
hope this will help you a little to solve your issue.

Can you put the ls -l output of any directory where the uids changed to numbers.
Thanks,

>>what can cause the uuid to change?
Main cause are user no more exist in your system. or your passwd file got corrupted.

Other cases are NIS where you need to:
# /sbin/init.d/nis.client stop
# /sbin/init.d/nis.client start
Or you could have problems with pwgrd(1M) and you have to restart it.

Re: uid and gid for /etc/password changed. var 100%
From system point of view everything will be dealed with uid and gid.
/etc/passwd file will be used to map the uid/gid with corresponding username and group whenever we list files and directories(for examable ls -al). If password file corrupts or owenership/permission changed then we may end of this kind of issue.
First you need to check the ownership and permission of /etc/passwd file and fix if improper ownership/permission.
You can run this command to fix improper ownership/permission to entire vg00
