Re: [MacPerl] ACGI Problems

[Dennis Little <dennis.j.little@lmco.com>]

Richard & Listers,

If you happen to find the solution to this one, let me know.  I've had a
similar but worse problem of lockups running a VERY simple cgi/acgi (take
information from the form and mail it to one address -- no additional
parsing needed).  After between 2-5 runs, my machine locks up completely
(no mouse movement, clock stopped, etc).

Just in case it matters (and for comparison), I'm running MacOS 8.5/8.5.1,
MacPerl 5.2.0r4 (17Apr98), no other applications running, 48 meg memory
with 5 meg to MacPerl, PM4400/200, Virtual Memory on for 1 meg (needed for
other reasons), using Apple Web Sharing.

I've tried re-installing Perl, clean install and upgrade to 8.5.1, and no
non-apple extensions/control panels.  Nothing seems to make any difference.

Good luck and if you come across ANYTHING that looks like it might be
causing this, PLEASE let me know.  This thing is time critical and I'm
about to be forced to copy it to Unix box to test & run.

Thanks,

Dennis Little
