OK. So, I just freshly formated my dev box. Reinstalled Ubuntu 6.06 LTS
(amd64), Java 6 (64bit), Tomcat 6.0.16 (with URIEncoding="UTF-8"), and
installed solr-1.2.0.
I'm still getting the same weird errors, but they have changed a little bit.
Below are the errors that are return as I hit refresh. It appears that the
error message is slightly differnet every refresh, "...start tag and not
XXX"... xxx changes between letters numbers and other random characters.
Also attached is the document I'm posting. I've posted this doc both from
coldfusion and curl (both are not multi-threaded). It will occasionally post
WITHOUT error. Although it's still random. What I've concluded is, this only
happens with a large post, if your only posting a few feilds it returns
succesful.
Let me know if I can provide any other details and I'll be happy. Thanks
Yonik!
Dan
