[parisc-linux] Squid freeze

[Bad Max]

Hi,

I've tried to run squid on my PA box under Debian 3.0. But squid freeze
at launch : it do nothing, it is simply frozen, it is not possible to parse
any line command (squid -v print nothing).

I did a dist-upgrade but nothing change. So I get the lastest version
of squid 2.5 and compiled it. Same symptom, squid is frozen. I did a
little modification to src/main.c in squid, in the main() function : I
took mainParseOptions() and put it in first of main() (it was executed
later after several others miscellaneous functions).

Now squid work perfectly. I suspect a bug in gcc, what do you think
about ?

In fact, I did a mistake because I did not resolve the problem by changing
the code but by adding the -X option to command line (it force full debug).

The -v option work without this option because of my change so there is
perhaps a bug somewhere in the code of squid (gcc ? squid ? libc ? don't
know for now).

I fixed a hang in the libstdc++ locking code on the weekend.  This
affects gcc 3.3 and later on PA 1.x machines.  Other than that,
there are no reported/known freezes caused by gcc.

Don't do this.

'dmesg' would inform you too that squid make a segfault?

I already report this problem in this ml and in Debian bug report (sorry
I do not remember # but it is easy to find back).

The problem was in fact due to a bad update of libpam-modules and a modification
in /etc/security/limits.conf which didn't occurs by default. You would found
tree line:
*       hard    core      0
*       hard    rss       5000
*       hard    nproc     20

which you can remove (what the update should do if you answer Y at this time)

Now, you have to quit completely your loging; login again and you should
now be able to use squid.


hth,

Sorry but there are no messages at all about squid in dmesg. I checked
/etc/security/limits.conf and the three lines you indicated are already
removed.

I repeat : I must pass the option -X (force full debug) to have squid
working. I will spend time tomorow to locate what seems to be at the
origin of this lock.
