34.2. Split Brain Timing: Detecting a Split

download PDF
When using the FD_ALL protocol a given node becomes suspected after the following amount of milliseconds have passed:
FD_ALL.timeout + FD_ALL.interval + VERIFY_SUSPECT.timeout + GMS.view_ack_collection_timeout


The amount of time taken in the formulas above is how long it takes JBoss Data Grid to install a cluster view without the leavers; however, as JBoss Data Grid runs inside a JVM excessive Garbage Collection (GC) times can increase this time beyond the failure detection outlined above. JBoss Data Grid has no control over these GC times, and excessive GC on the coordinator can delay this detection by an amount equal to the GC time.
