Hi all,
Sorry, this is a bit long.
I'm working on a bunch of machines running Solaris 2.6 on which I have
installed Apache+mod_perl static. The machines are set up for just a
couple of virtual hosts at present for testing, eventually they will
be load-balanced with mod_perl on separate machines and will host many
sites. I downloaded & compiled new sources for the latest (not CVS)
versions of Apache 1.3.12, mod_perl 1.24, mod_macro 1.1.1 and Perl
5.005_03. The compiler is gcc 2.91.66 and was used for all the
compilations.
I set up a plain/mod_perl Apache pair on one of the machines. The
proxying worked fine and I could get server-info and server-status OK
from the mod_perl Apache. I left it at that and went on to other
things. Unfortunately when the development department started working
on the scripting a couple of days later (yesterday, Friday) the
mod_perl Apache started segfaulting as soon as they tried to get it to
serve a request from their test handler. Here's the error_log message:
[Fri Jun 16 17:20:21 2000] [notice] \
child pid 22310 exit signal Segmentation Fault (11)
There is no core dump and the same thing happens with the -X switch.
The first Perl had thread support and dynamic linking, so I recompiled
it twice, once with no thread support and once without dynamic linking
but the same thing happened. Below are the makepl_args.mod_perl, the
output of perl -V, httpd_perl -l, perl.conf, startup.pl and test.pm
which I just noticed contains a call to Apache::Request->new() and I
don't know why. I don't think that should make Apache segfault...
I searched the archives and there are some Solaris segfaults but
nothing seems to fit this simple case. I don't have access to the
machines at the weekend so I've posted this hoping it might ring some
bells somewhere before I try again next week maybe with the CVS
version of mod_perl 1.24 and maybe even with 1.21 and 1.3.9 just to
see what happens. I'll also get rid of that Apache::Request call and
try things like Apache::Registry scripts to see what happens there.
Any input gratefully received. Especially by Leo, who gets it in the
neck if the machines aren't ready to go live next Friday...
73,
Ged.
