This is a weird one, validating http://lposun.larc.nasa.gov/ceresweb/INSTRUMENT/FM1_html/FM1_BRAKE_DEFINED_CAGED_MARGIN.html with the production v.w.o always gives me a "500 internal server error" seemingly without anything useful showing up in the server's error log. What makes it even stranger is that v.w.o:8001, qa-dev/wmvs/0.6 and my local validator instance all are fine with this document, no "500 i s e". ---- Folks, Attempts to validate the following URL is causing an "internal server error" http://lposun.larc.nasa.gov/ceresweb/INSTRUMENT/FM1_html/FM1_BRAKE_DEFINED_CAGED_MARGIN.html File size: ~368_145 bytes However, a virtually identical file (URL below) is not having any problems. http://lposun.larc.nasa.gov/ceresweb/INSTRUMENT/FM4_html/FM4_BRAKE_DEFINED_CAGED_MARGIN.html File size: 170_636 bytes Data of validation: 13 May, 2004 Time of validation: ~10:30 AM Eastern Daylight Time ~14:30 GMT (?) The formats of the files are identical as are the system permissions and the top level directory structures. The only noticeable difference is the larger file size. Otherwise I do not see any reason for the server failure message. Let me know how I can be of further assistance. Otherwise, please advise where/what are the problem(s). The W3 validation service is a very valuable tool in my web development endeavors. Respectfully yours, Phil Hess -- Phillip C.

I'm not sure if they'll end up being the same problem, but they seemed related enough to report it in this bug rather than opening a new one. We're attempting to validate a client site at http://www.malaprops.net. The validator consistently returns a 500 Internal Server Errror, but viewing the site from a variety of different browsers and operating systems is fine. We've combed through the Apache and Tomcat error logs and tailed them while reloading in the validator - we're not getting any error messages on our side at all. There isn't any further information in the validator error message that might help us track it down if it's not a bug, but maybe someone with acccess to the validator's logs might be able to help. (We did, incidentally validate the source using the indespensible Web Developer's Toolbar in Firefox and the "Validate Local HTML" - it does validate). Thanks! 8691 6 ot 2006-03-12 00:44:05 +0000 (In reply to comment #5) > We've encountered a similarly weird reproducible 500 internal server error > message. > We're attempting to validate a client site at http://www.malaprops.net.

Your site somehow does not like the (simple and correct) requests made by the validator. ~% telnet www.malaprops.net 80 Trying 216.154.208.55... Connected to malaprops.net. Escape character is '^]'.
