Well, "Out Of Memory" should be clear enough. Maybe the computer actually does not have enough memory to support what you're trying to do.
Two questions would be: do the two computers have the same amount of memory and are you trying to scan the same datafile with the same rom folders? If you wish to do a proper comparison between the two computers, you should make sure that you are doing the same thing on similar hardware resources.
If you eliminate that possibility, then there is a chance that the combination of datafile and romfiles you use has caused a hidden bug to appear, either in RC or in Wine. In any case, since in that case it would be a developer issue, only Eric could help.
Hey Wanderer!
Have a look at my previous posts where I was running RomCenter on a miniPC with 4GB or RAM.
Slow, but everything was working, also with a lots of rompaths added.
Now the problem is on my main PC with 16GB of ram!!
And on my main PC - for now - I have only two rompaths added...
