could not allocate pools

[denizyuret]

With the latest snapshot I cannot start more than 7 workers on a 16-core, 64GB machine. julia -p 7 works, julia -p 8 gives "could not allocate pools". My ulimit -a output is:

Could you please append the output of versioninfo()? Thanks.

Here you go:

Isn't this just #10390 ?

[denizyuret]

Yes, thank you. My search failed to find 10390 before, but the workaround suggested there (remove 16* from gc.c:164) solved the problem. I am closing this one.
