I'd bet it has to be in whatever receiver routine you are using. Either that, or the server is some how configed not to accept long posted content. Limiting the length of posted data is always desireable to stop flood attacks.
The other strange problem I found, which doesn't really relate to your issue, was that Opera won't transmit large chunks of text. I never pinpointed the actual limit, but I'm guessing it's somewhere around 1MB. Every other field would transmit fine, but the large textarea field would end up blank each time.
