Camel cache entries gone after certain interval

[souciance <so...@gmail.com>]

Hi,

I have implemented camel cache as follows:

		from("cache://cache1" + "?maxElementsInMemory=100"+
				"&memoryStoreEvictionPolicy=MemoryStoreEvictionPolicy.LFU"+
				"&overflowToDisk=true" +
				"&eternal=true"+
				"&diskPersistent=true")

All elements are set to eternal so they should stay forever.

However, we have noticed that every once in a while we when do a cache GET
the key entry that worked a short file ago is reported as not found.  A few
minutes later when the entry is added and we do a GET it works again. A few
minutes later it reports it as not found. Is there a parameter missing or
have I missed something?

Essentially we are just storing string key values.

Best
Souciance

I debugged the flow and saw this:

[d #2 - NettyEventExecutorGroup] CacheProducer                  DEBUG
Quering an element with key Login from the Cache
[d #2 - NettyEventExecutorGroup] CacheEventListener             DEBUG
Element [ key = Login, value=1, version=1, hitCount=0, CreationTime =
1455798324000, LastAccessTime = 1455798324000 ] has expired in cache cache1


So, somehow even though I have eternal to true, the element still expires?
