Indeed, the apache error logs seem to reveal something. The contents of
/var/log/apache2/error.log show the following:
Premature end of script headers: cgi
I followed up by trying to run the scheduler (bin/cgi) under the debugger.
When I run
gdb cgi
r < sched_request.xml
I get the following output:
Starting program: /home/boincadm/projects/full/cgi-bin/cgi <
/home/boincadm/sched_request.xml
[Thread debugging using libthread_db enabled]
Content-type: text/plain
<scheduler_reply>
<message priority="low">Server can't open log file
(../log_debian6/scheduler.log)</message>
<request_delay>3600</request_delay>
<project_is_down/>
</scheduler_reply>
Program exited with code 01.
Might it be a permissions problem? I tried making sure the group
permissions match up but it's not doing anything.
Any clue what the problem is?
