Bug 172014 – nfs-utils-1.0.12 rpc.mountd has a huge memory leak

• Status: RESOLVED DUPLICATE of bug 171844
• Product: Gentoo Linux

[Description Bardur Arantsson 2007-03-24 08:25:03 UTC]

The rpc.mountd in nfs-utils version 1.0.12 leaks memory like a sieve. On my nfs server (2 clients doing ... not very much) it would end up leaking around 1GB over 24h-48h.

This is apparently caused by a memory leak in e2fsprogs (which rpc.mountd uses as a library starting with 1.0.12). See http://article.gmane.org/gmane.linux.nfs/12887 for official confirmation from the upstream maintainer. :)

Two patches are needed to fix the leak, one against sys-fs/e2fsprogs and one against net-fs/nfs-utils -- both are referred to by the above mentioned post, but I'll attach them to this bug shortly (for your convenience).

Cheers,

nfs-utils-1.0.12-r1 now in the tree with that mountd fix, cheers

Sorry about the semi-duplicate (don't know why i didn't think to search for e2fsprogs :/), but #171844 doesn't seem to address the leak in rpc.mountd itself. This second leak is not nearly as serious, but it's still a leak and as such it should be patched.

Cheers,

Nevermind that. Didn't notice vapier's comment until it was too late :).

Thanks.
