Summary0006507: MySQL Deadlock / aServersData is written on every page view
DescriptionIf you use subshops, Oxid is deleting and inserting the aServersData entry in the oxconfig table on every page view which sometimes leads to MySQL deadlocks on our server.
Steps To Reproduce1. Call any page of shop 2.
2. Watch it renewing with this query: "SELECT * FROM oxconfig WHERE OXVARNAME = 'aServersData'"
Additional InformationOn line 216 the parameter gets written with shop ID 1, but it's always read shop-specific on line 46.

I could simply fix it by replacing the method call "getConfigParam" with "getSystemConfigParameter" on line 46 of the "oxserversmanager.php".

In enterprise demoshop it is not reproducable.
The aServersData entry in the oxconfig table was only inserted once, not on every page view.
Try to reproduce in new installation.

I could reproduce it in an 5.3.1 EE demoshop.
However you either have to configure the base url for a subshop or call the shop with a "shp" parameter in the URL and this also will only be reproducable when you delete the aServersData key within the oxconfig table for the subshop you are calling.

Well, I think we don't have that aServersData key for shop id 2 because we were migrating from 5.0.11 to 5.3.1. So I think this was missing in the migration script.
After the migration we created another subshop. And for this one we have that entry.
