I have been happly using mod_perl for more than a year. My
application uses the Apache::Session package. One day, July 4 to be
specific, my httpd_perl childs stated dying. The error log say:
[notice] child pid (...) exit signal Segmentation fault (11)
After putting a lot of prints to STDERR, I found that the processes
were dying at the following line of code:
untie(%session)
Where %session is the Apache::Session hash. This is very odd because
I didn't change anything on my dedicated server that day. And it is
also odd because sometimes work, sometimes fail. So far this is what
I have tried to do to solve this:
1) Recompile apache+mod_perl
2) run under mod_cgi. This results in "premature end of script headers".
I store the sessions in a MySQL database.
I will now give you more details of my configuration:
mod_perl: 1.29
apache: 1.33
perl: 5.8.4
mysql: 4.1.10a
Apache::Session: 1.6
Apache::Session::MySQL 1.01
CGI::Application 3.31
RedHat Linux kernel 2.4.20-37.9.legacy
Just for completeness, this is part of the code I am using.
my %session;
my $id = $q->cookie( 'COOKIE-NAME' ) || undef;
eval
{
tie %session, 'Apache::Session::MySQL', $id,
{
Handle => $self->param('mydbh'),
LockHandle => $self->param('mydbh')
};
};
if ($@) # if an error occurred, old session is unavailable; create
a new one
{
$id = undef;
tie %session, 'Apache::Session::MySQL', $id,
{
Handle => $self->param('mydbh'),
LockHandle => $self->param('mydbh')
};
}
I would really appreciate any help.
