Hi,
I've attached the relevant section of a client log after noticing load
problems due to the glusterfs process after an upgrade from 1.3.8 to
2.0.1.
The first warning about ulimit -n is due to the selinux policy not
allowing it by default (selinux is enforcing and will stay that way).
This denial has also been seen on the server, could it be related to
the issue?
avc: denied { mmap_zero } for pid=3155 comm="glusterfs2"
scontext=system_u:system_r:mount_t:s0
tcontext=system_u:system_r:mount_t:s0 tclass=memprotect
Any help would be appreciated.
Matthias
