Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Subject: RE: mod_perl 1.99_09 core dumps

Hi

It doesn't look there is a core file:

castle# find . -name core -type f -print
./t/core
castle# find . -name core -type f -exec ls -al {} \;
-rw------- 1 nobody nobody 9449820 Jun 23 09:54 ./t/core
castle# find . -name core -type f -exec file {} \;
./t/core: ELF 32-bit MSB core file SPARC Version 1, from 'httpd'

I run the make test at the 25th.

I removed the t/core file and run the make test again:

castle# \rm t/core
castle# make test
cd "src/modules/perl" && make -f Makefile.modperl
...
preconnection/note.t 1 1 100.00% 1
*** server localhost:8529 shutdown
*** port 8529 still in use...
done
!!! error running tests (please examine t/logs/error_log)
make: *** [run_tests] Error 1
castle# find . -name core -type f -print

I even checked the complete /usr/local/ partition. I did not find any core file
related to mod_perl.

I also get those kind of segmentation fault from time to time, if I stop apache
(without mod_perl) using apachectl, see e.g. the stop / start I did this
morning:

Yes I did, and from the output of the error_logs, I can see that httpd
is still segfaulting.

Could you please try and find those cores (or run in debugging mode) and
post a stack trace like last time.

Most lilely looks like my little duct-tape patch simply plugged one
segfault that's a symptom of something bigger being broken (as I
feared).
