Re: File handle limit?

I don't necessarily need 256k file handles, but I do need more than 10k (I have unit tests simulating normal behavior which are dying).

Sounds to me like a bug in the unit tests, or in the code being tested. In particular, the code should read and respect any limit that the process is operating under. If that means throttling the number of concurrent open files, then that's what it should do. Processes should operate properly within their assigned limits or degrade gracefully. If they can't, then the process is at fault, not the limit.


... but on linux this is as easy as ulimit -n <large>; java Application

Probably because Linux has higher hard-limits, or higher sysctl settings, or doesn't support those other limits at all.

Use 'ulimit -H -a' on a Linux bash and see what its hard-limits are. I doubt the fd's are really unlimited.
