Could not reproduce, occurred in multithreaded application with
ServerSocket and snaq.util.DBPool database connection pool to MySQL
database. The database connection was open at the time of the crash and
the ServerSocket was listening without any clients up to this point
according to the logfile (limited using only System.out, no logging
facility). The application would have been waiting in the
ServerSocket.accept() function. It is possible a client connect caused
this issue, in which case a ClientSocket would have been created and
started listening using the InputStream.read() function. Further system
information:
