Hello,

Im a linux newbie.. i faced a crash in squid2.4STABLE7 while adding ACLs by using webmin,actually what was there in the ACL is an empty DENY at the end of the ACLs,which i thought its something like EOF ,... after applying settings i got an error in that line,i managed to restore the squid.conf but no use! , squid keeps dying after starting

From cache.log:

Code:

I hope ur squid has corrupt....

You do onething....
mv squid.conf squid.old
and reinstall the squid by

rpm -ivh --replacepckgs  squid*.*

this will reinstall your squid
then add ur rules in squid.conf
and do the following

squid -z

this will solve ur problem

Hello..
I havn't been in such problem bfore but I have its solution lying in my computer. Here is...
-------------------
Some versions of GCC (notably 2.95.1 through 2.95.3) have bugs with compiler optimization. These GCC bugs may cause NULL pointer accesses in Squid, resulting in a ``FATAL: Received Segment Violation...dying'' message and a core dump.

You can work around these GCC bugs by disabling compiler optimization. The best way to do that is start with a clean source tree and set the CC options specifically:

% cd squid-x.y
% make distclean
% setenv CFLAGS='-g -Wall'
% ./configure ...

To check that you did it right, you can search for AC_CFLAGS in src/Makefile:

% grep AC_CFLAGS src/Makefile
AC_CFLAGS       = -g -Wall

Now when you recompile, GCC won't try to optimize anything:

% make
Making all in lib...
gcc -g -Wall -I../include -I../include -c rfc1123.c
...etc...

NOTE: some people worry that disabling compiler optimization will negatively impact Squid's performance. The impact should be negligible, unless your cache is really busy and already runs at a high CPU usage. For most people, the compiler optimization makes little or no difference at all.

Thank you! for ur replies, but the re-installation didnt solve the problem, neither the steps for the compiler optimization thingie!

i think its something to do with memory,, but how?!!
