Nodejs App Using Gearman Gets Stock In the Process

I need an expert to take a look at a Nodejs app that uses Gearman. Context: The main server has external servers that connect to it to process multimedia content, this is done using the gearman service, the remote server connects to the main server on port 4730 (only certain IPs can connect on that port), also the remote server can connect to the main server's Mongodb. This is done so that more processing power is supported by having external resources (other server running the same software) can also take on workload. Challenge: Our problem right now is that for some reason the processing is getting stuck halfway, so any time a multimdia content is sent for processing, it doesn't complete that processing. We can restart the services (worker services specifically) and processing will restart but will not complete again. Please only apply if you have experience working with Nodejs and Gearman and if you can take a look at this right away until it you find a solution. This is solution needs to be proveen that it works (because you've tested), it needs to be documented so that we know what to do if something like this happens again, specially in other environments. Start your response with "Bonjour".
