squid problem
 

hi i have squid running in my network the problem i am facing is that once a week the squid service is dead, i checked the log files bu could not figure out what the problem is it gives me the error
squid dead but pid file exist
squid error no running copy

i have written a script that just moves the compressed log files from the /var/log/squid files to /media/usbdisk the script is as follows i suspect that this problem arises because of the script coz the script runs every week and the next day i get this problem

#!/bin/bash
cd /var/log/squid
YMD="`date +%d%b%y`"
echo "------------------------------------------------" >> ~/squid_script/log
echo -e "backup of squid logs on $YMD\n" >> ~/squid_script/log
echo "------------------------------------------------" >> ~/squid_script/log
for file in a*.gz
do
echo -e "renamed file $file to $file$YMD " >> ~/squid_script/log
mv $file /media/usbdisk/squid/access/$file$YMD
echo -e "file $file$YMD transfered to /media/usbdisk/squid/access/ \n" >> ~/squid_script/log
done

for file in c*.gz
do
echo -e "renamed file $file to $file$YMD " >> ~/squid_script/log
mv $file /media/usbdisk/squid/$file$YMD
echo -e "file $file$YMD transfered to /media/usbdisk/squid/cache/ \n" >> ~/squid_script/log
done

for file in s*.gz
do
echo $file
echo -e "renamed file $file to $file$YMD " >> ~/squid_script/log
mv $file /media/usbdisk/squid/store/$file$YMD
echo -e "file $file$YMD transfered to /media/usbdisk/squid/store/ \n" >> ~/squid_script/log
done
echo "------------------------------------------------" >> ~/squid_script/log


please if anyone find something that is causing the problem in the script please rectify it for me me.

please help me on this issue

Maybe it is because you move the log file so squid dont find it anymore and freezes? Just a gues though . .

What is the purpose of your script?
Is this in an aide to reduce disk usage?

I would agree withmarkotitel as it seems you move the file to the new location which in effect breaks the connection that
squid has to all these logs.
I would be guessing but it appears you would have to do something like empty the contents into a file on your USB drive rather than break than connection

yes your absolutely right, the script is to reduce disk utilization
how do i overcome this , actually i move the files which are rotated weekly not the current log files ,
even i had the same feeling but was not sure, any way to overcome this as my hard drive gets full with the squid logs weekly
