Red Hat kernels patch (server-tuning.patch or similar in the
SRPM) NR_TASKS to 4090:
[pmatilai@chip linux]$ grep NR_TASKS tasks.h
#define NR_TASKS 4090 /* On x86 Max 4092, or 4090 w/APM
configured. */
so unless it's a custom built kernel chances are it's something else.

One other possibility is that you've run into the maximum open
files-limit which by default is 4096. The cure for that is very easy
though, just do
echo 8192 > /proc/sys/fs/file-max
There should be something about this in the logs ('maximum open files on
system reached' or so) if this is the reason for your problem. (Seen this
recently myself..)
