First step, if you know the server they are getting dropped from, run dmesg. Look for any NICs going up or down.
Another thing I like to do is enable some of the DTU logging features, but it's important to set the log host to a Sun Ray server that you're not experiencing connectivity problems to. You do this by setting the following key/value pairs in your parms file LogNet=7 LogHost=hostname or IP of Sun Ray server The value of the logging levels are 1 through 7. Larger number = Greater Verbosity. http://docs.oracle.com/html/E22661_15/Clients-Howto-Prepare-Config-Files.html#parms-Key-Value-Pairs On May 20, 2013, at 8:23 AM, "Nishimura, Scott L (ESS)" <[email protected]> wrote: > Simon, > > I've run into this a few times also but have never found a definitive way of > solving it.
