Shiny server disconnecting apps

Question

We had shiny server running on an i686 machine under Ubuntu 16.04. After a recent upgrade server does not run the apps we were using to read and plot data from a MySQL database.

Now when we try to connect to our server the shiny app appears but in 1-2 seconds the screen goes to grey and a disconnected from server message appears

As there are no precompiled binaries for our system we have followed instructions to build from source at Rstudio github site. It apparently runs fine.

Shiny process is up and running

ps -ef | grep shiny
root     13596     1  0 10:19 ?        00:00:01 /usr/local/shiny-server/ext/node/bin/shiny-server /usr/local/shiny-server/lib/main.js --pidfile=/var/run/shiny-server.pid

status shiny-server
shiny-server start/running, process 13596

But at /var/log/shiny-server.log this error message appears

[2016-12-09 09:39:18.692][ERROR] shiny-server - Error getting worker: TypeError driver.validateOptions is not a function

Any idea of what happens with our server? Thanks in advance
