Re: Re: Re: Re: Process exists - Segmentation fault
Hi,
I was getting some bizarre seg faults with embperl a month or two ago.
The site used to work fine, then it started segfaulting all over the
place after I did a new linux install. I started erasing huge blocks
of code until I found the code responsible: for some reason, having a
BEGIN {} block in my base.html, with a few use's and such in it, was
causing seg faults. I moved that code into startup.pl and it stopped
segfaulting.
I have no idea if this applies to you, Abhishek, but I just wanted to
share.
Greetings,
Allen

Hi Gerald,
Sorry for a late reply ,
no make test did not worked correctly, it did tested the modperl part and
gave error like an error on line 21.
I will try to give the exact error later,
Thanks,

Hi,
Maybe we should go one step back:
Does make test works correctly for you?
Does it also test the mod_perl part?

Hi Its me again,
But still the things are not working right.
I tried to recompile Embperl and put PerlModule Embperl after
LoadModule embperl_module ..
Now i do not remember it was before or now but after i
uncomment the 'PerlModule Embperl' line and things stop
working i do not receieve $r=shift; variable i mean $r = undef here.
Is it due to something i did during installation of embperl.
Also If i uncomment the line 'MaxRequestsPerChild 1' and
comment 'PerlModule Embperl ' then i recveive this line in
error log [Sun Jan 06 18:44:11 2008] [notice] child pid 30280
exit signal Segmentation fault (11)
(May be error and page refreshes itself i mean the code
produces output.)
and page appears , sometimes the same error appears twice and
page does not appears.
I am not sure have this error been encountered by someone
else but things are not working right for me . Also if
someone wants i can mail the Embperl logs to someone
individually, i do not want to make the logs public.
Pl help. I am working on the site http://delhi.pm.org/ it is
the delhi perl mongers site and people in this group have
limited knowledge of embperl but this will push up the
embperl in Delhi .

Hi,
Not sure if it makes any difference, but the lines
LoadModule embperl_module
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/Em
bperl/Embp
erl.so
PerlModule Apache::DBI
PerlModule Embperl
Should be outside of the VirtualHost block (they are
global anyway)
The other thing that you should make sure, is that
mod_perl is compiled
with the same Perl that Embperl is and both are using
modules from the
path /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi
If there is any version mismatch, things cannot run correctly.
