I think this might be from a cronjob running the sar command to collect
system info to graph (CPU, free ram, cpu temp, etc). Some of the data
gathering is only seconds long, however it spawns a new instance of `sar
-u` or `sar -B`, etc.


My mail server is doing the exact same thing when running fetchmail for
several accounts. Every few minutes cron rolls through 4 or 5 accounts,
runs fetchmail, and terminates leaving all those `elogind` messages in
syslog.

It may be since I'm using bash in the scripts called by cron, this is
creating a login shell. Could that be what's causing all this noise?

Thanks and apologies for the belated reply
