We are using melt utility to flatten vidoes. in it there is a plugin called kdenlivetitle. this plugin imposes title text on video but it requires X server. for that we are using xvfb-run but it hangs in-between sometime. Below is the output of "ps"
root@ip-10-112-249-15:/home/ubuntu# ps -ef| grep melt

could it be because of this command running simultaneously? if it is i can restrict it to one at a time.
if you require any of other log or output please provide me how to get it.
Thanks in advanced.
