FTP Adapter stops polling files intermittently due to timeouts when reading from FTP server

The problem is preceded by timeout issues deleting files, eg. There are repeated FTP errors such as:

    Unable to read response
    Error deleting file from FTP Server
    FTP command DELETE returned unexpected reply code : 550
    Caused by: java.net.SocketTimeoutException: Read timed out
    
Eventually the Adapter shuts down with the following error:

    PollWork::run exiting, Worker thread will die
