FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory

[hbmartin]

When I try to minify large (several MB), I get the following error:
FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory

googleing around shows that this seems to happen when node is running code with memory leaks. Indeed, the node process running ycssmin uses >600MB memory prior to erroring.

Anything I can do to identify the source of the memory leak?

How big is this CSS file? Can I get a copy to test it with?

[hbmartin]

The file is ~5MB. This is a company CSS file, so I can't post a dump of it :(
However, I found I could reproduce the problem by duplicating a 100kb or so of CSS repeatedly in the same file.

I'll take a look at this sometime tomorrow.

@hbmartin Not sure if you solved this issue, but we ran into it yesterday.

Just now we've discovered that for us the issue was with having less generate comments.

We were checking the memory size of the node process during execution, and with comments generation turned on, the process hit 1.2GB and blew up. When we removed comment generation, the same process topped out around 55 megs.

Hope this helps!

I'll just chime on in, nigh 2 years later, that I was having the same error and turning off line comments in compass (my CSS preprocessor) fixed the issue as well.
