I noticed that you are using CFI filter with FTOCL:

 |05/07 04:03:26.62 [5201] 0+0: ext[184] FTOCL=/proxy/relay/cfi/8080.cfi

Maybe your CFI is conditional on Content-Type or so, therefore your log
does not indicate the invocation of FTOCL CFI.
But when DeleGate is running with FTOCL of CFI, It is certain that DeleGate
stops relaying response message to the client until DeleGate completes
receiving the response data.  (I'v fixed it to break receiving with FTOCL
of non-CFI in DeleGate/8.7.7).

The problem can be fixed as the enclosed patch.
I uploaded the patched version as DeleGate 9.8.2-pre30 to the FTP server.

Cheers,
Yutaka
