exited due to signal 25 (squid Error)

[SOLVED]

Hi Guys ,

Some times back I have faced some problem in one my squid proxy server. My squid service was killed and was failed to start the service. 

# service squid start

Starting squid: ....................                       [FAILED]

There was no visible error on that screen. It simply returned the status is failed. Then I check the log file of system. There was an error "exited due to signal 25".

I was confused. First I clear the cache. After that I have tried again and again to start squid. But it always FAILED.  Then i did some googling. I find some information from web says that "That may be because of bigger log file". If your squid log is larger than 2 GB then it will create problem to start squid. then i checked my squid logs. 

# du -sh /var/log/squid/*

1.5G /var/log/squid/access.log

375M /var/log/squid/access.log.till20120425

1.7M /var/log/squid/cache.log

0         /var/log/squid/cache.log.log

688K /var/log/squid/log5.txt

2.1G /var/log/squid/store.log

Found my store.log is more than 2 GB. So i decided to clear the log. 

# cat /dev/null > store.log

#

After clearing that log i have started the squid again. Its simply started without any problem. 

# service squid start

Starting squid: .                                          [  OK  ]

Thank You... :)
