Hi,
I have strange crash in httpd.
I use a modified version of httpd to include modperl, because some
perl module
are not happy with the dynamic loaded one.
I do not use SSL on this http server, so I do not understand why I
got this kind of
crash. Every few minutes a httpd child crashs. The bt command gives
all the time
the same call path.
I take a look on Google and found
http://article.gmane.org/gmane.comp.apache.mod-ssl.user/3987
that look like my problem.
I check http_main.c and the patch is already applied on OpenBSD 3.8.
I have build the system with stable patch and WDT activated.
Any help is welcomed.
Jean-Gerard
