L class server not responding



We have a L class server,which is not responding after some time.We are able to ping
at that time but unable telnet or to access
from the console.After turning off and ON..it works properly.
Observation made:
one of the file system(volume group) is 100%
in size(it is a home directory volume).

Any suggestions..

Hi,

Check the /var/adm/syslog/syslog.log file for errors, check the /var/tombstones/ts99 file for errors.

If $HOME is full, no wonder no one can telnet in. You need to log in as root and determine why the filesystem is 100% full. Clean up the filesystem or expand it, then monitor the situation.

In addition check the syslog for further errors.

Re: L class server not responding

I hate to agree with Cheryl, but space can very easily be the issue here. Check /var/adm/syslog/syslog.log to see if any errors exist. then I would clean out cores from the /home directory. I would then look to see if anything is causing the problem via a
du -sk /home/*| sort -n and then further drill down to find any files that can be removed or relocated and access granted via symbolic link.

Only after getting the system available I would look to expanding the filesystem especially if this is a production server...
