This can occur when control-reset is pressed in P8 mode. It’s supposed to reinitialize the AppleTalk stack. In our case, we mark connections to be reset once we're back in GS/OS, since we can't call Marinetti in P8 mode.
This only works if our init is loaded before Marinetti’s, because otherwise Marinetti’s shutdown notification procedure gets control first and shuts down the connection.
This issue arises because ASP requests and replies are limited to a “quantum size” of 4624 bytes even if the amount requested is larger, and the AppleShare FST relies on this behavior in sizing its buffers. DSI does not have this limitation, so it was returning more data than would fit in the buffer.
Also improve error checking, so an error is reported in cases where the buffer is too small.
