[exim] Understanding of smtp_load_reserve

[Patrik Peng via Exim-users]

Hi there








What time span does Exim use for the average load calculation?


Regards
Patrik

We have a few FreeBSD hosts running Exim with something like `smtp_load_reserve = 30` configured and occasionally see dropped connections because of high load: 2022-02-11 10:02:07 temporarily refused connection from [1.2.3.4]: not in reserve list and load average = 30.74 But according to our monitoring system (which tracks 1min and 15min avg), the affected hosts never exceed an average load spike of 20. Could it be possible, that it uses a shorter time window and there are short load spikes exceeding the limit of 30 or is there a possible bug?
