Re: /var/adm/messages size

limit is filesystem limit ;-)

no it will not affect the performance (maybe only for seeking to end of file).

Please use the command

# cp /dev/null /var/adm/messages

Re: /var/adm/messages size

You may want to consider using a utility like "logrotate",which is available forLinux and some other unix flavours. This way you can preserve old versions of the /var/adm/messages file for a certain period of time that would be critical to diagnose errors happened in the past.

You might as well write a simple shell script to do the same and run via cron on a regular basis. Again consider avilable free space on /var filesystem before implementing these scripts. Peroformance won't be impacted.

Re: /var/adm/messages size

why not simply use a crontab entry? You don't need special application for that so lowering administration...

Re: /var/adm/messages size

It will not affect anything if you deleted it. However, I recommend to keep a copy just for reference if you needed to go through logs of old reboots

Re: /var/adm/messages size

I guess you should do a good housekeeping for system logs, incl:
/var/adm/messages, /var/adm/binary.errlog

On certain ocassion the java's desta process uses 100% of CPU when the binary.errlog is huge.
