Max Document size

I am using LiveCycle ES2.5 Turnkey,

and I am getting the following warning in JBoss server log:

2011-03-31 21:09:58,367 WARN  [com.adobe.formServer.common.cachemanager.CacheManager] Ignoring cache write as Object size is greater than Max Document size in cache setting. Key [repository:///Applications/AAll/1.0/E11.xdp] and Size [1197072]

How do I increase the size in cache setting?

thanks
