One SteveJobs job trigger can no longer be triggered after temporary MongoDB connection issues, but another one can

[skluyskens-azumuta]

A few days ago, we experienced MongoDB timeout issues for approximately one minute. After this incident, one of our jobs could no longer be triggered, while another job could without issues. My assumption is that somehow the queue crashed, but I don't know how that could happen.
We have one Meteor server with autoStart false and one with autoStart true (to force the jobs on one specific server).

Stack trace that I found back, but I don't think that's the issue.
