Hi, I've just install a mdk9.1 (with httpd2) and written my vhost.conf file. I work on Koha (www.koha.org), that is a Perl programm (not mod_perl, but CGI). MARC::Record, yaz-2.0, Net-z3950.0.33 and some other perl packages installed. Everything works fine, except on a few pages, that shows "waiting for ..." forever. The error log only show (after 2mn): [Fri May 02 17:04:40 2003] [error] [client 127.0.0.1] Premature end of script headers: search.pl, referer: http://127.0.0.1:7777/cgi-bin/koha/acqui.simple/addbiblio.pl?oldbiblionumber... If I close the mozilla windows, after 3 or 4 more minuts, the log is suddenly filled with dozens of : [Fri May 02 16:56:52 2003] [error] [client 127.0.0.4] Use of uninitialized value in hash element at /usr/lib/perl5/site_perl/5.8.0/MARC/Record.pm line 206., referer: http://koha.dev/cgi-bin/koha/acqui.simple/addbiblio.pl?oldbiblionumber=8 Note it occurs only on a runtime error in the module. In case of a compilation error, the error is reported immediatly as previously. It's a bug in Koha, but with my previous install (http1.3 from mdk90), The errors where reported immediatly to the error log. At the moment, it's pretty unuseable for error tracking ! What happend ?
