Problem is that I use a 5.2 Sitecore, and when I start to publish something, it only shows the publishing window and a "Queued" message. There is a chance that some people full published several times(that means 15000 items and 4 slaves), and the publishing queue is stuck. The restart of the webserver/app pool is not an option. Any experiences in sitecore publishing errors? something like this
If several full publishes are queued then you will have to either wait and see if things finish or recycle the AppPool to start over. Try checking your Sitecore logs to see if there is any information in there that will tell you if publishing is actually locked up or if it is just taking a while to finish.
In my experience it is possible to see that locked up publishing dialog and still have the publishing queue clear itself. Unfortunately though you will most likely have to recycle the AppPool to fix this issue.
