> In MasterController#appendLog, log is force-sent to the slave if the
> replication log buffer becomes full. However, the log chunk that should have
> been appended is discarded:
> try {
> logBuffer.appendLog(greatestInstant, log, logOffset, logLength);
> } catch (LogBufferFullException lbfe) {
> try {
> logShipper.forceFlush();
> } catch (IOException ioe) {
> ...
> }
> The log chunk must be added after freeing a log buffer by calling forceFlush
