POE Client Http: "expected a request ID, but there is none" error

tofu has asked for the wisdom of the Perl Monks concerning the following question:

Hi --
I'm using POE to check links, using code derived from Randal's column ( http://www.stonehenge.com/merlyn/LinuxMag/col41.html ). I'm encountering the same problem reported by Matt Trout here , named a "expected a request ID, but there is none" error, or sometimes an error "Cannot call method previous on an undefined etc". This occurs after a (seemingly) random number of HTTP requests.

Any suggestions? Thanks

UPDATE -- to clarify, the code is basically Randal's code, with only slight slight modifcations: instead of passing URLs around in POE as strings, I pass Class::DBI objects from a URL table, and pull off the actual destination when I need to fetch it. Again, the code works, sometimes for minutes and 50 or 60 URLs, and sometimes for an hour and many 100s or 1000s of URLs, but then dies mysteriously with an error from deep w/in POE. I cannot detect anything special or unusual about the URL(s) it is working on when it dies.
