java.lang.OutOfMemoryError: GC overhead limit exceeded

[Andrius St]

Hi,

I have discovered sdfs only yesterday and immediately wanted to try it on my Windows system. I successfully created a volume and copied my games on it and got great dedup rates. Perfect!

The problem: after an hour or so the volume become pretty much inaccessible. Explorer keeps freezing for 3-4 minutes before it show anything related to the volume. CPU usage is going through the roof (3 cores fully loaded by Zulu Platform x64 Architecture program (java.exe process). The console window that I mounted the volume with has the following output:

============================================

C:\Program Files\sdfs>mountsdfs -v sdfs_vol1 -m S

Running Program SDFS Version 2.0.11

============================================

The RAM usage on my system is 8.2GB out of 32GB (only about 1.5GB used by Zulu Platform x64 architecture).

Java is version 8 update 45 x64. (none 32bit versions installed)

Just to explain - I understand Windows environment is not tested much so this is more of a test report than complaint. If there's a work around I could try to continue testing - great I would like to try it. If not yet then I'll be patient and wait.
