Hi,
I am running modperl 2.x + embperl on centos 4.5
Now when i run on
MaxRequestsPerChild 1
the app. runs well
but as i increase its value after every third refresh of browser a blank
page appears, also the process size exceeds probably to 19M , and in
error_log segmentation fault error appears.
I believe the size exceeds some threshold.
Now is there a way to increase the value of MaxRequestsPerChild ?
Can i increase the threshold value of size of a process or so ?
Thanks,
Abhishek jain

RE: Process exists - Segmentation fault

Hi,

Apache with mod_perl will always have this size or even more. This is=20
ok.

ulimit -a shows the process limits, but should normaly not a problem

The behaviour you describe occurs when you do _not_ have a LoadModule=20
_and_ a PerlModule statement for Embperl in your httpd.conf

Hi,
I have the following statement in my httpd.conf

LoadModule embperl_module
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/ Embperl/Embperl.so

I do not have a related PerlModule just one for Apache::DBI .
Thanks,

RE: Re: Process exists - Segmentation fault

Please add a=20

PerlModule Embperl

Somewhere _after_ the LoadModule

Hi,
Adding PerlModule Embperl did not solved the problem , infact it aggreviated
it. With this the page is not didsplaye at all.
My apache configuration is:

:80>
SuexecUserGroup "#" "#"
ServerName xxxxxxxxxxxxxxxxx
ServerAlias www.xxxxxxxxxxxxxxxxx
DocumentRoot
ErrorLog

RE: Re: Re: Process exists - Segmentation fault

Hi,

Not sure if it makes any difference, but the lines

LoadModule embperl_module=20
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/ Embperl/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=20
with the same Perl that Embperl is and both are using modules from the=20
path /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi

If there is any version mismatch, things cannot run correctly.

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 .

Thanks

RE: Re: Re: Re: Process exists - Segmentation fault

Hi,

Maybe we should go one step back:

Does "make test" works correctly for you?

Does it also test the mod_perl part?

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,

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
