Any attempt to run a nodejs based job with jsub fails with the same message.
Jobs are submitted like this (test.js is just a console.log statement).
jsub -l release=trusty node test.js
The result is this error is printed to nodejs.err
FATAL ERROR: v8::Context::New() V8 is no longer usable
This could be a memory issue; the default memory allocation for jobs is 256MB, and not all VMs handle malloc() failing well. I suspect the node VM might be one of them ;-)
For reference, grrrit-wm uses
jsub -l release=trusty -N lolrrit-wm -mem 1G -continuous node /data/project/lolrrit-wm/lolrrit-wm/src/relay.js
i.e., it requests 1GB memory rather than 256MB. I would suggest trying the 1GB option, and maybe decreasing it if qstat shows it doesn't quite need that much.
You're right. I also tested with 500MB before, but it looks like Node.js requires 1GB of ram even for something as simple as this script:
console.log('...');Yes, this seems to be a more generic thing with VM-based languages; the same happens for Java and (less so) for Ruby and Python. For Node, the memory usage is ~670MB VMEM (which includes all shared libraries that are loaded, so that's much more than the incremental usage of a single process), while the resident size is only 11MB.
In any case, please don't worry about requesting 1GB of vmem; we've got enough space :-)
