rtmpdump fails if download takes too long: Download may be incomplete...,try resuming

[cheche]

if a download takes too long rtmpdump exits with this message:

Caught signal: 13, cleaning up, just a second...
ERROR: WriteN, RTMP send error 32 (42 bytes)
ERROR: RTMP_ReadPacket, failed to read RTMP packet body. len: 68763
20194.415 kB / 134.13 sec (59.5%)
Download may be incomplete (downloaded about 59.50%), try resuming

errno 32 is EPIPE. the error appears both compiled with openssl or gnutls (not tested with polarssl).
the Wireshark trace looks like this:


if i play the video with the player on the website it doesn't cut the connection.
