One way to work around this is to rebuild the util-linux package without the offending patch. The patch that is causing you grief is against mount. Last time I tried to locate it, it was fairly obvious. It does RPC probes to the servers it expects to mount. This causes around 6 or more reserved ports to be used for each attempted mount. Possibly more in your case or maybe you have a bunch off mounts which fail. Last time I exersised this I was able to get just over 120 mounts before the pear took shape.
