Hi, I've got a problem with the replication of the cache. I put a big Map (about 4 MByte) to the cache. On the local cache everything works fine. But it doesn't get replicated to the cache on the other cluster member. I don'T get an error nor an exception. The map only has four key/value-pairs. But under every pair there is another Map and under this again another Map. My configuration is REPL_ASYNC and REPEATABLE_READ. Map<String, Map<AttributeName, AttributeProperty>> tempGroupCache; ...fill tempGroupCache from the database... this.tree.put(this.TREECACHE_NODENAME_GROUPCACHE, tempGroupCache); Is there a problem with the replication of big maps?
