On startup of our app we get the error message

! Error: 04/08/15-15:20:55 PDT: WARNING: Your ehcache offheap cache configuration (plus an additional 268435456 overhead) is 530579456 bytes. This exceeds the JVM -XXirectMemorySize (524288000). Your application may experience OutOfMemoryErrors.

In ehcache.xml we have the

maxBytesLocalOffHeap="250M"

So when setting --XXirectMemorySize we have to include the offheap we want (250M) plus "additional overhead" correct? Is "additional overhead" a fixed value or is it proportional to maxBytesLocalOffHeap?

Thanks
