I've got an intermittent error that's giving me a real headache.

It happens at the first line of my servlet's doPost method (request.getParameter) and returns a java.lang.RuntimeException: Read of HTTP Request POST parameters failed: read < content length

I've seen this mentioned several times in the archive, but I haven't seen any solutions. I'm thinking that the content length is getting bashed somehow. I'd like to be able to diagnose the problem, but I'm not sure where to look.

Any thoughts about how to diagnose or deal with this gracefully would be most appreciated!

Here's the basic info about my system...
Tomcat 4.1.24
Apache 1.3.29
mod_jk
RedHat Linux

All of the errors have occured with IE 6.0, but that may just be a coincidence.

Here is the stacktrace...
