Pipeline hangs

[iron_guitarist1987]

Hello all,
I have a pipeline that hangs for a couple of minutes and then it starts running normally. I think it may be my sink element, but I'm not sure. This is the debug message I get when it starts hanging

Here it hangs for some time, and after a couple of minuts it starts running again. This is the debug message I get after:

Then it starts running normally.

Any ideas?
