-- Alain Spineux <aspineux@xxxxxxxxx> is rumored to have mumbled on 17. November 2007 00:46:43 +0100 regarding Re: Bingo!:
I tested the timeout using a SSL connection and a normal connection and get two different result ! The SSL was working as expected but the normal one "timeout" in a different way, it get a SIGTERM ! I will repeat the test Here is the normal one : # telnet localhost 110 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. +OK eg01.emailgency.loc Cyrus POP3 v2.3.9-openpkg server ready user alain.spineux@xxxxxxxxxxxx +OK Name is a valid mailbox pass ******** +OK Mailbox locked and ready list +OK scan listing follows 1 1779 . # I dont send anymore command for 10min and wait for the timeout ! Connection closed by foreign host.
That's OK. Just to make sure: the problem I had noticed on my server and which we were trying to nail down did *not* occur for sessions where a login had been done. It only happens for sessions where the client does nothing or goes away *before* a login (or actually a successful SSL negotiation) has happened.
Here is the strace from the list command
read(0, "list\r\n", 4096) = 6
time(NULL) = 1195253508
write(13, "<1195253508<", 12) = 12
write(13, "list\r\n", 6) = 6
open("/kolab/var/imapd/msg/shutdown", O_RDONLY) = -1 ENOENT (No such
file or directory)
select(1, [0], NULL, NULL, {0, 0}) = 0 (Timeout)
time(NULL) = 1195253508
write(13, ">1195253508>", 12) = 12
write(13, "+OK scan listing follows\r\n1 1779"..., 37) = 37
write(1, "+OK scan listing follows\r\n1 1779"..., 37) = 37
time(NULL) = 1195253508
select(1, [0], NULL, NULL, {600, 0}
) = ? ERESTARTNOHAND (To be restarted)
#
# HERE IT IS WAITING FOR 10min AS EXPECTED
--- SIGTERM (Terminated) @ 0 (0) ---
Process 5720 detached
I dont understand why it got a SIGTERM !
Neither do I. I tested the same thing and I got this trace:
Process 18811 attached - interrupt to quit
select(1, [0], NULL, NULL, {565, 380000}) = 0 (Timeout)
time(NULL) = 1195297357
close(9) = 0
munmap(0xb47a7000, 4096) = 0
unlink("/var/lib/imap/proc/18811") = 0
...
So everything looks fine here.
