There was a bug in the handling of (ftpd):
#ifdef TCP_NOPUSH
/*
* Turn off push flag to keep sender TCP from sending short packets
* at the boundaries of each write(). Should probably do a SO_SNDBUF
* to set the send buffer size as well, but that may not be desirable
* in heavy-load situations.
*/
on = 1;
if (setsockopt(s, IPPROTO_TCP, TCP_NOPUSH, (char *)&on, sizeof on) < 0)
syslog(LOG_WARNING, "setsockopt (TCP_NOPUSH): %m");
#endif
#ifdef SO_SNDBUF
on = 65536;
if (setsockopt(s, SOL_SOCKET, SO_SNDBUF, (char *)&on, sizeof on) < 0)
syslog(LOG_WARNING, "setsockopt (SO_SNDBUF): %m");
#endif
That caused the kernel to panic for certain ftp transfers (small mtu, I think).
Fixed now :)
