Description Viraj Alankar 2001-01-25 19:58:50 EST
When having the following in root's .bashrc:

ulimit -n 90000

starting portmap, then doing rpcinfo -p causes portmap to crash. Also doing

strace /sbin/portmap -vd

segfaults on a select call with a very large file descriptor set. I don't
know if this is a bug in glibc or portmap. Any help appreciated.

It tries a huuuge select call, and dies doing that... jakub?

Note - none of this happens on a rawhidish system w/2.4 kernel and glibc 2.2

Fixed in newer versions of Red Hat Linux.
