    distributedSyncTimeout setting

    craig bomba Novice

      I'm still struggling with some issues.  Have not heard much in my posting on Multicast discovery with multiple clusters.  As I try to understand why I am seeing strangeness with my testing I now focusing in on the transport setting for distributedSyncTimeout. 

       

      I am using the ALPHA3 distribution.  I have 2 JVMs in a replicated cluster.  I am loading some 100,000 entries into one of the JVMs before bringing up the 2nd JVM on another machine.  I start the 2nd JVM and it gets the 100,000 entries since I have the fetchInMemoryState set to true.  That works.  However, on occasion I do not see new entries in the first JVM get propagated to the cache on the 2nd.  Other times I do see this working.  Additionally, when simulating a failover I have witnessed a situation when brining the failed JVM back up it gets hung on the getCache call.  Including a stack trace at the bottom.

       

      First, can someone give an idea what that setting actually does? 

       

      And, is my assumption correct the unit is milliseconds??
