Hi
I have big problem with soft bounces. Take a look for following transaction
log (I have change dest mail to fake one):

Dec 17 12:03:39 www postfix/smtp[17276]: vstream_fflush_some: fd 13 flush
After that the smpt proces hangs on poll syscall. Because I have a lot of mail
to send, eventually all available smtp processes will hang. This
cause "active" queue to stall - almost no mail are delivered. Only way to
make some delivery mail is server restarting. Because eventually
all "deliverable" mail are gone, rest only those greylisted (and other 4xx).
In this case postifix restart give only some delivery - but I have thousands
mails wait in queue!
I have trace problem by debug build and gdb. This is a call backtrace:

Please note that read_wait call has file descriptor equal to -4 - it looks
very _strange_ to me, especially that source code indicates that this value
should by equal to timed_read parameter ('13').
lsof tell that '13' is unix socket:
smtp 25061 postfix 13u unix 0xe0cb3b00 313337814 socket
Can you tell me what's going wrong?
