Memory leak nfs-ganesha
by akarchagin2012＠gmail.com
Good morning everybody. Does anybody can help me in case on memory leak of nfs-ganesha?
After 4-7 hours of copy files from local disk to nfs share I catch OOM killer because of nfs-ganesha use all hosts memory.
I've changed all parameters in my ganesha config file in MDCACHE block - nothing is changed - memory leak is present. Please help!!!

Proxy-v4 access denied
by Nehring, Shane R [LAS]
Hello all
Background:
running 4.0.6 compiled from source, rpms distributed from our satellite
I'm attaching the ganesha.conf and the export in question
I've been trying to get proxy-v4 to work in a test case. Permissions of the upstream export should be good, I'm able to access
it as limited users and root. However, when I try to access the mount (ls the mount or stat a file under it) I get Permission
denied. Initially I thought this was due to the ol rpc 16 group limit, and I needed to turn on Manage_Gids, however enabling
that hasn't helped. I also tried with a user with fewer than 16 groups with no change.
I've got full_debug logs on for FSAL, NFS4, and EXPORT, but nothing in the logs is really jumping out to me. I've made selinux
permissive for the ganesha_t type with no change.
Based on a network capture it really does seem like ganesha is the source of the denial, I don't see any traffic to the upstream
nfs server during the denials.
Hopefully this is simply some configuration error on my part, I'd be grateful for any pointers.
Thanks
Shane
