[SQU] POST fails with files > 1024 K

hi all

this problem appeared at our site with squid 2.3STABLE1:

uploading files > 1024 K (exactly!) from localdisk to a remote webserver via
POST request fails. (netscape reports a broken pipe, i/o error while writing to
the network; msie simply issues a generic error page). tcpdump shows the squid
machine sending RESETs after receiving some packets from the browser, and not
sending anything to the webserver. no log entries at all, not even at debug
level 9.

as far as i can tell, the POST originates in some java function called by
pressing the appropriate button on the form.

the only parameter i have found is request_size, which was commented out in
squid.conf (btw, what is the hardcoded default?).
setting it to 10M and restarting the squid didn't change anything.

and, even stranger: the same config and upload work well with any prior version
(tested with 2.2S3 & S4 & S5)

any pointers are very welcome
