[Mailman-Users] Internal Server Error - only sometimes

[Matúš Petruľák]

hello!

i am running debian woody with apache 1.3.26 and mailman version 2.0.11
both are default in debian woody

and when i am administrating mailinglists or when i just visit 'listinfo'
page i sometimes get Internal Server Error. But only sometimes. For example
when i refresh 'listinfo' page for the 7th time i get ISE.

in /var/log/apache/error.log:
Premature end of script headers: /usr/lib/cgi-bin/mailman/listinfo

in /var/log/apache/suexec.log:
[2003-12-26 11:43:50]: info: (target/actual) uid: (root/root) gid: (root/root)
cmd: listinfo
[2003-12-26 11:43:50]: crit: cannot run as forbidden uid (0/listinfo)

i chceckd the permissions of listinfo, but i get only this and i think it is
correct

-rwxr-sr-x    1 root     list         5596 Sep 18  2002 listinfo


Please can you help me, or tell me where did i make a mistake?
Thanks.
