Have you tried to open _different_ files? j@uriah 226% limit desc unlim j@uriah 227% limit desc descriptors 680 j@uriah 228% perl -e '\ sub xopen {\ local($i)=@_;\ local(*F);\ $i++;\ if(open(F,">foo$i")) { &xopen($i) }\ else { print "Got $i files.\n"; }\ unlink("foo$i");\ }\ &xopen(1);' Got 487 files. Oct 29 22:13:03 uriah /kernel: file: table is full Oct 29 22:13:03 uriah /kernel: file: table is full My maxusers is 20, this makes 680 descriptors -- the value you can see after ``limit unlimited'' above. > PS: Please send me your answer as an email.
