Subject: memory leak in autofs-4.1.3-114 on FC3/i386?
Date: Fri, 29 Apr 2005 03:20:54 +0200	[thread overview]
Message-ID: <20050429012054.GA17598@neu.nirvana> (raw)

Hi,

an updated FC3/i386 box with mail server functionality accesses
O(1000) accounts over NFS (NFS server is a dated Tru64 Unixcluster).

The automount process consumes memory until we have to kill it, or the
machine starts oom-killing us. Here is a graph:

(We have also seen bad behaviour of rpc.idmapd in the past, and 200MB
looks a bit too much for mapping 1000 accounts)

As a side note: Even though there are only 1000 accounts on this
system, mounts are attempted on each forged incoming address,
e.g. there is a multitude of failing mount requests, perhaps that's
causing the large rpc.idmapd process space and automount's memory
consumption?

Anything else we can provide for debugging? Thanks.
