I user xvfb on my Ubuntu servers mostly to run browsers in Selenium QA automation. I user this servers to test web applications, so I run A LOT of browsers. But after some time errors appears like

xvfb-run firefox
xvfb-run: error: Xvfb failed to start

I tried 

xvfb-run --auto-servernum firefox

but got same error

I think there is some problem with initialization some resources, which use xvfb, because after server reboot xvfb works fine for some time. So I want these resources reinitilized after this error, but I don't know how

Found the problem There is hanging process in system with name

Xvfb

I killed it and work fine. I newer found it earlier beacuse I used to try to find process with 'xvfb' name
