Some more info on this - I was looking around my logs files, and found that I 
also saw this message in Tomcat 4.1.24, but there was a different, longer error 
message: Invalid argument
         at Method)

although, it appears that at the time this error message was generated, Tomcat 
was throwing an OutofMemory error - I'm not sure if one had anything to do with 
the other, but judging from the date on the log, that was an error we were 
getting often at that time...

Hope this helps!
