Hi,
I have a exim4 configuration running queuerunner=separate in 15min
intervals. At present, the server accepts subscription mail from a local
server and sends mails every hour. I had trouble with errors relating to
connection refused and too many connections. Upon further reading, I have
set the values as follows:
smtp_accept_max=1500
smtp_accept_max_per_host=500
smtp_accept_max_per_connection=700
smtp_accept_queue_per_connection=700
smtp_accept_reserve=300
The errors seemed to stop. However if I decrease the value of
smtp_accept_max_connection and smtp_accept_queue_per_connection to less than
500, I still keep getting errors such as connection refused and too many
concurrent connections especially at 9:00 in the morning when more number of
emails are sent.
Eximstats generated the report giving a value of 1973 messages received
between 9 and 10 AM today. This is the actual number of messages received
everyday at this time. Most of the emails are actually received at 9 and
9:01 itself and mostly from a single local server.
The problem is whenever exim4 delivers the messages every hour especially at
9, 10 and 11 every morning, the load shoots up to 95. Is there any way I can
tweak the exim4 config so that the load is not very high. By the way exim4
is configured to use a single configuration file.
Any help will be greatly appreciated.
Thanks,
Praveen
