Thanks Ted.

I didn't see the log . I have filed a issue(HBASE-4028)) and uploaded the log.
I will make a patch and please review it.

主题: Re: Hmaster crashes caused by splitting log.

In doRun():
        try {
          writeBuffer(buffer);
        } finally {
          entryBuffers.doneWriting(buffer);
        }
totalBuffered being negative implies that there were exceptions in
writeBuffer().
Did you see the following in log ?
        e = RemoteExceptionHandler.checkIOException(e);
        LOG.fatal(this.getName() + " Got while writing log entry to log",
e);

Thanks
