Hi,
I have an out of memory problem with meteor (current meteor 1.4), and I’m not sure about the cause.
I write a lot into mongo collections (query a third party service and process/store the data) and output a lot of lines to the server log. My UI uses collections as reactive sources and displays for example the current count or the last processed job.
But what part most likely caused this?
The last log output on server side is:
I20161104-08:23:13.733(1)? CLUSTER PROCESSING FOR ID FMBNSPB_qtXAQkPykD9Rqr IS FINISHED

=> Exited from signal: SIGABRT
Because it happens in transport.js it looks to me like server-client communication (changes in collection that are pushed to the client?!?) caused that nodejs died. Any suggestions? What can I do about this?
