Description marinalan 2009-12-15 17:53:57 UTC
Summary:

SELinux is preventing /usr/bin/memcached "write" access on memcached.pid.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by memcached. It is not expected that this
access is required by memcached and this access may signal an intrusion attempt.
It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2009-12-15 19:40:39 UTC
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
