Dockbar is temporarily unavailable workaround

Issue

• Suddenly, while navigating or performing an action, an error like "Dockbar is temporarily unavailable" appears.

Resolution

Usually this error, if it doesn't happen consistently, is a consequence of performance issues. So, how should you proceed?

1. Check the log for relevant errors.
2. If no relevant errors appear most likely it must be caused by performance issues. In this case you should perform a two steps approach:
   1. Analyze the infrastructure performance. This article is useful to start.
   2. Meanwhile increase layout.parallel.render.timeout to avoid the timeout failure. This should only be temporarily until you find the cause of the performance problems.

#
 # Set the timeout time for server side parallel rendering. On timeout,
 # all pending portlets will fail back to ajax loading or trigger an error
 # message depending on whether the portlets are ajaxable.
 #
 # This timeout is an int value rather than long to avoid some atomic set
 # race condition. The Integer.MAX_VALUE is more than enough for a reasonable
 # timeout.
 #
 layout.parallel.render.timeout=5000
