apache child dies under mod_perl
Hi !
I'm having a problem under mod_perl , when my script is executed under
cgi-bin I don't have any problems, but under mod_perl I have a SIGABRT.
![Tue Jan 15 17:03:41 2002] [notice] child pid 27481 exit signal
Aborted (6)
Probaly I'm having problems with mmap system call, in the
implementation of the Debian's glibc nothing wrong has occurred ! But in
RedHat ... (both are under mod_perl 1.26)

I had tried change the version of perl to 5.6.1 , but the problems
remained.
Somebody could help me ??
Thanks !!

Did you recompile mod_perl after doing this?
Did you compile Perl and mod_perl with the same compiler?
