Subject: NFSv4 and Kerberos problem in svcgssd
Date: Sat, 16 Jun 2012 00:30:28 +0200 [thread overview]
Message-ID: <20120615223028.GS20917@ics.muni.cz> (raw)

it seems that -n option for rpc.svcgssd produces file descriptor leaks. It
looks like this:
ls -l /proc/25920/fd/

Is there any known fix for this? It runs quickly from max open files..
There is some gabage collecting that results in this:
