something unusual is occurring since two weeks ago I┬┤ve beed deleting big files in /var/spool/cron/tmp but I can only see the efect of using "rm" when rebooting the server.
Please can somebody explain to me why, why this big files are all of sudden there. I appreciate your help on this.
Although I pass the CSA exame I dont have a lot of experience on the field, so please help if you can.
regards

Re: bdf shows same value after deleting stuff in /var
Your challenge now is to try and identify those processes and stop them if you are able or it is sensible to do so. The easiest way to do that is to get hold of a copy of lsof if you don't have it already:
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.84/
You can then run:
lsof +aL1 /filesystem
To find all "unlinked" files on the filesystem which are still open, and the processes holding them open..

Re: bdf shows same value after deleting stuff in /var
#cd /var
#find . -xdev -size +10000 -exec ls -lrt {} \;
before deleting the file check the timestamp
#ll
remove the file. If you see that again the file is there then check the time stamp. May be after deletion again its created automatically. so please check the timestamp before &after deletion.

Would be right to say that the files that I deleted are related to:
sshd 916 root 3u unix 64,0xa 0t0 0 4099 /var/spool/sockets/pwgr/client915 (0xbc6173c0)
lpsched 1560 lp 3u unix 64,0xa 0t0 0 4137 /var/spool/sockets/pwgr/client1557 (0xbf6c8c80)
So what will be the next step?

Re: bdf shows same value after deleting stuff in /var
I├В┬┤ve read on another post in the forum that files with link counts = 0 (NKINK) they will be ones that are still in use by a process and are thus holding disk space. If this is correct all those processes shown by lsof command must be killed?
Am I right? Please help
regards
F.R.

SolutionWell, only the ones with large files.
You'll have to determine whether the space is more important than the process.
You seem to have a lot of process by ora10g referencing these large stdout files:
586861075 0 9780
586936815 0 8460
586897644 0 9090
570483566 0 9355
>Would be right to say that the files that I deleted are related to:
Not really. Those seem to be sockets?

Re: bdf shows same value after deleting stuff in /var
Space is more important, so I├В┬┤ve killed just one, the biggest, but still when I do bdf it shows /var as 97% as it was before.
I├В┬┤ve used "kill PID number" to kill the process.
I need that space to go down up to 70%,
