Ok found a temp work around. Basically what I found is that on fast systems the problem doesn't always show as eopkg has time to clean up its tmp files. When you scroll through the list in solseek fast, it is calling eopkg info every single time.
Here is where it gets fun. Every eopkg info call creates a onefile_ directory with a bunch of data including the eopkg.py3.bin into /tmp, which you can see in the screenshot of one below. They are all different based on the package and some can be quite large. This is not an issue when you are calling eopkg info manually as it has plenty of time to do its garbage collection. When you are hitting the down arrow on solseek and launching off dozens every second, well that can be a problem.
So what I am doing is adding a sleep for the preview so that it doesn't actually get to call the eopkg portion unless you stop on a package. It will cause a slight delay.
I think another step is to see if there is a more efficient way for with eopkg on this. May peek around that end as well.
Right now I will get a quick patch out to fix this.
Here is the example of a onefile_ directory that gets created for every item...
