Rakesh R commented on ZOOKEEPER-1844:
-------------------------------------

I think I found the problem, please see the analysis. In this case, snapshotting has happened and created new log file. But the rolledover log file is kept open, this is causing the test case failure.

FileTxnLog.java
{code}
    public synchronized void rollLog() throws IOException {
        if (logStream != null) {
            this.logStream.flush();
            this.logStream = null;
            oa = null;
        }
    }
    public synchronized void close() throws IOException {
        if (logStream != null) {
            logStream.close();
        }
{code}

Following logs shows the rollover and snapshot operations:
