Hi Fred,
I imagine that your high load is due to running many instances of
HAProxy, but hard to be 100% without all the information.
Load indicates that there are processes waiting to execute, so by
reducing the number of HAProxy processes you should see a reduced load
(but still high cpu utilization).
You can accomplish the same effect as reloading settings by running
another HAProxy process with the -sf parameter (this would potentially
lead to more load, but could be mitigated by combining your many
instances).
>From the manpage:
-sf <pidlist>
Send FINISH signal to the pids in pidlist after
startup. The processes which receive this signal
will wait for all sessions to finish before exiting.
This option must be specified last, followed
by any number of PIDs. Technically speaking, SIGTTOU and
SIGUSR1 are sent.
Cheers,
Jeff
