Re: cfservd memory/file handle leak?

[christian pearce]

There are definitely problems.  We simulate configs of 10,000
machines.  By the end of the day we has 512M used up by cfservd.  We
are running 2.1.15.  I have not had a chance to try and track it down.
 It is actually pretty tough to do this.  I know there are tools, but
I am not up to speed on them.
