squid dies after every 5 to 10 mins (squid dead but pid file exist)

**sureshk** · 09-18-2012

Hi,

Squid proxy is running on Cent OS 6, recently we installed squish for the squid, every time when the squish.cron.sh (runs for every 5 mins.) . squid status says " squid dead but pid file exist."
Its too difficult to restart squid every time..
any help please ! !

Can you show the contents of the squish.cron.sh script?

Maybe try running squid in the foreground, w/debugging enabled, e.g.:

Code:

squid -N -X

Is there anything helpful in the logs (/var/log/squid/*)?

Is there an update to the squid package for your version of CentOS? I see that there is an update for 6.3:

http://mirror.centos.org/centos-6/6....6_3.x86_64.rpm

before installing squish it was nice, but after installing squish its happened. i'll try to update the OS.
squid.out log:
squid: ERROR: Could not send signal 0 to process 32560: (3) No such process
squid: ERROR: Could not send signal 0 to process 3328: (3) No such process

sorry forgot to mention squish.cron.sh
pls find code.

Code:

#!/bin/bash

# squish.cron.sh  -- Quick and DIRTY squid log analysis
#
# Assemble squid logs, and send through squish.pl.  This script gets run on a
# regular basis.  It will install itself in crontab if you give it a chance.

that is a very convoluted script.

in order to troubleshoot, i would start squid in the foreground, like I mentioned above, then run this simpler version of the above code:

Code:

#!/bin/bash
for log in $(find /var/squid/logs /var/log/squid /usr/local/squid/var/logs -name "access.log"); do
  printf "\nLOG: $log\n"
  cat $log | /path/to/squish.pl
done

just make sure that you change /path/to/squish.pl to reflect where that script is located on your system.

also, make sure crond is not running, to prevent the original squish.cron.sh from running concurrently.

Because of Internet problem I am giving reply lately.

I run the simple code which you given and its run properly and the users were squished with this code it self.

And I did not find any errors and the squid runs properly when I disable squid.cron.sh

what should be the next step that I have to do.?

sorry for the late response...

so if it works for you like it is code, you can try running it in cron, instead of the other script. i'm not sure where your cron job is located, do you know where it is? If you don't, try looking in /var/spool/cron/root and the /etc/cron.* directories.

thanks for the reply..
cron job was located at /etc/crontab
I gave permissions for the code which you given as 755
and I added like in to cron job ..

Code:

*/5 * * * * root /usr/local/squish/squishing.sh

and tried also like this

Code:

*/5 * * * * /usr/bin/sh /usr/local/squish/squishing.sh

The problem is it's executing properly when I run manually but not working through the cron job.

Cron Log :

But it is at least getting called by the cron daemon, right? At least per the log entry above.

Or are you saying that it does not appear to be getting called by the cron daemon at all?

Btw, your first cron entry is the one I believe is correct (the one specifying "root" user), although the other one may work on your system. Typically crontab wants that field to be a valid username.

In order to try and see what is going on, you can redirect the cron job output to a log. something like this:

Code:

*/5 * * * * root /usr/local/squish/squishing.sh > /tmp/squish-cron.log 2>&1

then after 5 min, check the log in /tmp for output.

I did as u said
out put log :

Code:

find: `/var/squid/logs': No such file or directory
find: `/usr/local/squid/var/logs': No such file or directory
LOG: /var/log/squid/access.log
Can't locate rrdsquish.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/squish/squish.pl line 25.
BEGIN failed--compilation aborted at /usr/local/squish/squish.pl line 25.

I looked at squish.pl but didn't understand the problem of rrdsquish [Contd..2nd page]
