Hi, I'm running Apache 2.2.6 on Windows 2000 SP4, and every once in a while, trying to get a page will return status 500 Internal Server Error "The server encountered an internal error or misconfiguration and was unable to complete your request." etc... If I then refresh the page in my web browser, it'll display fine. I've checked the logs, and don't see any more details on the error. The access log has: 10.1.1.66 - Dave [13/Nov/2007:11:57:26 -0600] "GET /trac/ HTTP/1.1" 500 545 The error log doesn't have anything with that timestamp, nor does it have any error that seems relevant--just a bunch of stuff like [Fri Nov 09 13:28:18 2007] [error] [client 10.1.1.66] (20025)The given path contained wildcard characters: access to /*docroot*/images/diff.png failed, referer: https://svn.azeotrope.org/viewvc/Azeotrope/Source/ShipmentPreparation/ShipmentPreparation.frm?r1=19631&r2=19630&pathrev=19631 and occasional lines like: [Fri Nov 09 16:17:20 2007] [error] [client 10.1.1.89] Provider encountered an er ror while streaming a REPORT response. [400, #0] Other than the default set of modules, the server is also running mod_dav, mod_dav_svn, mod_python, mod_ssl, mod_ldap, and mod_authnz_ldap. (However, mod_python is a recent addition; I had the same problem without it). I have a feeling that the problem might be related to mod_ldap, but it's just a hunch. It's authenticating against a Windows 2003 machine. All requests to Apache use https. Is there any more info I should provide? Or any way for me to get more info? In particular, doesn't the error log normally show a real error message when the server returns status 500?
