Question

I installed 4.0.4 plus hotfix 2 on HP Itanium, and set up Apache from the generated file, and configured TWiki with no errors or warnings. When I attempt to register the first time, however, I hang during the submit.

I am hanging in TWiki/UI, line 78, on the line:

read(STDIN, my $buf, $content_length, 0 ) if $content_length;

$content_length is 308. I enabled script logging in Apache/mod_cgid.c and forced an error just before the read to capture the request. The full request is:

Does anyone have any ideas or suggestions? I've been working this for almost three days now. Any and all additional

Other Notes

Apache is built 64-bit IA64, and perl is built 32-bit IA64. I upgraded List/Util.pm and Scalar/Util.pm from CPAN, since the versions I had did not recognize refaddr

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

This appears to be an Apache problem, rather than a TWiki configuration or perl problem. using mod_cgi.c rather than mod_cgid.c resolved the problem (although I did not discover the root cause).

See Bugs:Item2753 and also Bugs:Item2753. And see TWikiOnApache2dot0Hangs

This problem is nasty. We are fighting an Apache bug by making a work around and this work around creates new problems.

We cannot just ask people to upgrade Apache and I am not even sure that cures the problem completely.

We either need a better fix for this issue or at least we need to make the work around conditioned. But what is then the condition?
