I am running a server with CentOS 5 with Plesk 10.1.1 (64-bit). The only change to the system recently has been upgrades to Plesk. I am having awful problems with doing a mass mailing recently.
When I run a test script using the php mail function in a simple script it takes 5 seconds to complete ( sending one email ).
When I tested sendmail with
strace sendmail -t leo@gmail.com < test.msg
The pause seems to occur on the wait4 command.
write(4, "Date: 16 Mar 2011 00:11:57 +0000"..., 190) = 190
close(4) = 0
write(6, "Froot@s15321728.onlinehome-serve"..., 62) = 62
close(6) = 0
wait4(25648, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 25648
--- SIGCHLD (Child exited) @ 0 (0) ---
exit_group(0) = ?
My knowledge of server is rather limited, could someone point me where the issue might lay?
