[Bug 46675] Black Ops 2 zombies mode crashes with Too many open files after 30-35 minutes of gameplay

--- Comment #19 from Anthony Jagers  ---
It seems that the uplay client is leaking file descriptors. It has been
shutting down for no apparent reason, while downloading a 29 gig game. Just
closing.   I ran the client at the terminal and intercepted the same line
reported by tjb in his first post.

err:winediag:FILE_CreateFile Too many open files, ulimit -n probably needs to
be increased

I'm looking for a more permanent way to increase  'ulimit -Hn' rather than the
proposal given in  comment #16. A kernel boot parameter perhaps? 
/proc/sys/fs/file-max gives 1630210  since I have 16 gigs of memory.
