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 -XX

irectMemorySize (524288000). Your application may experience OutOfMemoryErrors.

In ehcache.xml we have the

maxBytesLocalOffHeap="250M"

So when setting --XX

irectMemorySize 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

Figured this out. Once I cut the "rest-management-private-classpath"path from ehcache-ee-2.6.6.jar everything started working correctly with no more exceptions.

Seems this error comes from ehcache-ee-2.6.6.jar which comes with BigMemory GO 3.7.5. When I remove it the error goes away but instead ehcache complains that the EE is needed for local off heap support which is understandable.

java.lang.Exception: java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: net.sf.ehcache.CacheException: Cache shopCache cannot be configured because the enterprise features manager could not be found. You must use an enterprise version of Ehcache to successfully enable overflowToOffHeap.

I'm getting the impression that standalone is not compatible with BigMemory-GO?

I have ehCache standalone setup and running and working fine using the REST interface. I want to now add Bigmemory support but am hitting some problems. I noticed on the standalone help page that I need to use a Bigmemory version less than 4 so I found 3.7.5 for my test.

First problem I ran into was an XML parsing error once I added the maxBytesLocalOffHeap attribute to ehcache.xml. I assume this is because the standalone ships with ehcache-core-2.0.1. I switched it out with ehcache-core-2.6.8 but am now getting the following exception.

Do I need to update the jersey jars? Any help would be appreciated. Thanks
