Excellent, thanks.

I have already gone over 512m, I am around 700 and I would prefer to avoid increasing this value as I think it might really leave very little memory to bubbleupnpserver and to the s.o. And basically I am compromising the linux disk caching already (buff/cache are very low).

The library is quite big as it resides on a 8tb seagate archive drive, filling it to around 85%. In time I have created tons of upsampled version of albums and never deleted one.
But the worst offending aspect are IMO the multiple tags I have created to further classifly my library. Infact, after dropping some of them which I was not really using, memory usage dropped to a safer 300MB or so.
