<div class="moz-cite-prefix">How are you getting the sample? Is it
possible that you're accidentally blocking the pipeline?I think
you're supposed to use "pull-sample" to get the new sample, but if
you call "pull-sample" where there is no sample, it will block,
and depending on how you're running your pipeline, that could
block everything. That's just a guess though, since you're not
showing very much of your code.<br>
