Version: 2.6.3-1.3.12
OS: WinNT 4.0 SP 5
Submission from: (NULL) (194.74.29.3)
Running winnt binaries from Randy Kobes (mod-perl build) Perl 5.6.0,
mod_perl-1.23, mod_ssl (2.6.3-1.3.12)/OpenSSL (0.9.5a), Apache_1.3.12
Intermittently (approx 1 in 1,500 page requests on cyclic load testing) Win-NT
generates an Access Violation message.
I have been unable to reproduce the fault reliably but it is consistent in the
location of the error.
Output from Dr. Watson is shown below, edited to show relevant areas. Please let
me know if other detail is required.
Apologies if something is missing, I'm not very familiar with debugging at this
level (more of a Perl coder!).
Can anyone provide an explanation and/or work-around for this error ?
Regards,
Simon Wilcox
