okay. it's my fault. i let the log file get huge--but deleting
it doesn't recover the space on the partition!
i made a reference in a perl script, called by the httpd server
(apache 1.3.9), that was undefined, and "perl -w" logged it
to the /var/log/apache/error.log file.
for some reason it logged and logged and logged that error
until it ate up the whole partition. i'll figure that out,
later.
so two apache processes are spinning their wheels trying
to log this error to a full partition. no problem:
# apachectl restart
poof, the troublesome apache children went away, and all is well
again in web-land.
after checking error.log to see if any useful info was in
there (yeah, right), i do:
# df

# cd /var/log/apache
# ls -l error.log
-rw-r--r-- 1 www-data www-data 437281392 Apr 26 22:00 apache/error.log
(cool! 437 [decimal] megabytes in one text file!)
# rm error.log
# ls -l error.log
ls: error.log: No such file or directory
even so, apache may still have a filehandle open to the file, so:
# apachectl restart
/usr/sbin/apachectl restart: httpd restarted
# sync
hell, let's be paranoid and shut it down completely:
# apachectl stop
/usr/sbin/apachectl stop: httpd stopped
# apachectl stop
/usr/sbin/apachectl stop: httpd (no pid file) not running
# ps ax | grep apache
9747 ttyp0 S 0:00 grep apache
yup. it's dead, jim.
# apachectl start
/usr/sbin/apachectl start: httpd started
# sync
now we should have over half our /var partition free again, right?
# df

i'm guessing that another process actually has the file open?
which one--or how could i find that out, myself?
if not, then--help!
