Re: [Bluemusic-users] Problems with Blue 2

[Steven Yi <ste...@gm...>]

Hi Mark,

I was able to reproduce here after increasing the size of the library.
 The cause was an OutOfMemoryException.  Wow... I just realized the
default settings for blue2 have very low memory maximums: This can be
modified in blue/etc/blue.conf and change "-J-Xmx64m" to something
like ""-J-Xmx256m" or "-J-Xmx512m" (or greater).  I will set the
values to the same as what is in blue 0.125.0 which looks like min
256m and max 768m.

Could you try updating this value and seeing if that remedies the
problem for you?

Thanks!
steven
