Re: [silk] OutOfMemoryError When Running Silk

[Robert Isele]

Hi,

the overflow of the PermGen-Space when doing hot reloads is a well-known issue in Java 7. You can solve it by either increase the PermGen space (see documentation of sbt) or by using Java 8 (preferred, replaces PermGen with a more solid solution).

Cheers,

Robert
