Out of Memory - process "analog"

Hello Piwik team,
I would like to ask what I can do with my Piwik install(s) as we have two running on one domain it is kind of hard too know what install is causing the issue, but mainly they are setup the same way.

For some reason it seems that sometimes the serverload on my cPanel Server is skyrocketing, until it reaches level near where the server gets unresponsive.

In the night it happened again, this time it was an OOM for the process "analog".

Shortly after that came an other message:

Both install use the stable release and are up to date.

Piwik 1

Piwik 2
Visits: ~4.500
Pageviews: ~12.000
Settings: Archive if shown in Browser: Yes, archive every 3600 Seconds
Delete old Logs: Yes + Delete if older than 30 days
Remove old Archives: Yes + Remove if older than 3 Month, keep basic stats

So I guess it will properbly the more huge one that causes the problem, will it be solved by simply changing the Settings to archive every 3600 seconds?! .. That would be kind of strange, as the problems were when noone used Piwik, so no achiving was started (thats how I understood it at least, Archiving only if Piwik opened with Browser)

Having every now and then the server load up to the point where nothing goes anymore isn't really what I wanted, so every help is really appreciated!
