0001607: aMule crash when you add a large (>1000) amount of file hash

Description

It seems that 1006 entries in paused mode is a ceiling.

here is the stack:

what(): OS_Rng: open /dev/urandom operation failed with error 24

GUI crash, amuled crash too
I know that situation is quite extreme but something must be done:
- fix a limit
- or correct the bug (if any)

Thanks for aMule, this is great soft.

Notes
(0003448) GonoszTopi (administrator) 2010-07-02 02:36	"open /dev/urandom operation failed with error 24" error 24 is EMFILE (Too many open files). The limit comes from the OS so we can't just fix it. However, we can make aMule keep less files open at the same time. Actually, we did it already. Until the next version gets released, you can try out the fix in a development snapshot from http://amule.sourceforge.net/tarballs/ [^]
