Description of problem: SELinux is preventing (vnstatd) from using the 'nnp_transition' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that (vnstatd) should be allowed nnp_transition access on processes labeled vnstatd_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
