Subject: Re: kern/17154: need to raise file descriptor limit, its 1024 now. i did sysctl but cant get FD_SETSIZE to raise

Synopsis: need to raise file descriptor limit, its 1024 now. i did sysctl but cant get FD_SETSIZE to raise

State-Changed-From-To: open->closed
State-Changed-By: alfred
State-Changed-When: Tue Jun 6 02:19:56 PDT 2000
State-Changed-Why: 
FD_SETSIZE can be defined at compile time of userland programs,
from sys/types.h:

/*
 * Select uses bit masks of file descriptors in longs.  These macros
 * manipulate such bit fields (the filesystem macros use chars).
 * FD_SETSIZE may be defined by the user, but the default here should
 * be enough for most uses.
 */
#ifndef FD_SETSIZE
#define FD_SETSIZE      1024
#endif

If the user is speaking of the kernel max file descriptors this is an
unfortunate limitation, but can be worked around via boot time config
and/or kernel recompiling.
