Unless you're running the bbs as 'root' (and I hope you're not), this isn't really relevant. You need to adjust the open file limit for the user that sbbs is run as:

Unfortunately, lsof is not accurate with multi-threaded programs since it'll list/count all open files for the process, repeated for each thread of the process. So lsof will report a much larger number than the actual number of open files.

No. I suspect you just haven't correctly adjusted your open file limit for the sbbs user/process yet.
