[peruser] file descriptor 1078 is too large

[Charlie Creed]

Hello All,

Recently I have started to get this error message:
[Sun Apr 23 13:34:26 2006] [warn] new file descriptor 1078 is too large; 
you probably need to rebuild Apache with a larger FD_SETSIZE (currently 
1024)

I know what this means but shouldn't it be killing the old file 
descriptors to make room for the new ones?

Any ideas?
Thanks,
Charlie
