Hi Andrew,

This doesn't seem to be related to the httpd Timeout config -- it's failing 
well before the five minute cut off.  That it happens after almost exactly 30 
seconds (30 seconds and a few microseconds each time) I think there must be an 
arbitrary setting somewhere.  I've tried the connecting with wget (which is 
supposed to wait 900s before failing) and it still dies after 30.  A simple CGI 
doesn't have this problem, so I think it's probably being set somewhere in 
mod_perl or embperl.

The page could run for as much as a minute before output is completely 
assembled.  I've optimized the code a bit and it now executes in under 30 
seconds, but the duration of the run is dependent on user supplied data (how 
many entries they make in the DB being queried), so that's no guarantee.

I've looked into the docs for the optEarlyHttpHeader setting you mentioned, but 
it seems to be removed in v2.0+.

Thanks much,
Matt

The timeout on the apache side is controlled by the "Timeout" variable
in your config file. Under debian at least this is set to 300 (5 min) by
default. Have a look at /etc/apache2 or wherever your apache config
files live and check the value.

If you're talking directly to the server (no proxies etc) then this
should be the culprit.

As an aside, how long are you expecting the page code to take?


In HTML::Embperl there was an optEarlyHttpHeader setting for
EMBPERL_OPTIONS. I can't see that available for Embperl and I'm not sure
its even possible with the structural changes made along the way. I'm
sure someone else with more experience in 2.2 can enlighten us though.

Cheers,

Andrew
