Hello,
I have quite strange problem. It's lsof -i -n -P
postmaste 20018 postgres 6u IPv4 12241380 TCP
127.0.0.1:5432->127.0.0.1:6651 (CLOSE)
And there is no pair for it.
Backtrace of the backend shows:
(gdb) bt
#0 0x40198ba2 in recv () from /lib/libc.so.6
#1 0x80ab2c5 in pq_recvbuf ()
#2 0x80ab395 in pq_getbytes ()

Looks like it tries to read on socket which is already closed from other
side. And it seems like recv did not return in this case. Is this OK, or
kernel bug?
On the other side I see entries like this:
httpd 4260 root 4u IPv4 12173018 TCP
127.0.0.1:3994->127.0.0.1:5432 (CLOSE_WAIT)
And again. There is no any corresponding postmaster process. Does anyone has
such expirience before? And what can be the reason of such strange things.
