com.sleepycat.je.rep.InsufficientLogException

This exception indicates that the log files constituting the Environment are insufficient and cannot be used as the basis for continuing with the replication stream provided by the current master.

This exception is typically thrown by the ReplicatedEnvironment constructor when a node has been down for a long period of time and is being started up again. It may also be thrown when a brand new node attempts to become a member of the group and it does not have a sufficiently current set of log files. If the group experiences sustained network connectivity problems, this exception may also be thrown by an active Replica that has been unable to stay in touch with the members of its group for an extended period of time.

In the typical case, application handles the exception by invoking {@link NetworkRestore#execute} to obtain the log files it needs from one ofthe members of the replication group. After the log files are obtained, the node recreates its environment handle and resumes participation as an active member of the group. @see NetworkRestore
