    LinuxShield 1.6 - logepo segfault

      Running LinuxShield 1.6.0 on a dozen SLES10 SP3 servers - deployed and managed by ePO 4.5 server


      Two of the servers have shown several segfault errors against the 'logepo' process (/opt/NAI/LinuxShield/libexec/logepo), though this process appears to stay running..!

      Any thoughts or suggestions?!?





        • 1. Re: LinuxShield 1.6 - logepo segfault

          Looks like this could have been to do with missing rights.... It appears  the 'nails' lum user had lost its file system rights to the root of one  of the cluster volumes, so we were getting thousands of scan errors  (5102) - this was probably overloading the 'logepo' process, which I am  guessing is responsible for reporting scan details to epo.
          Anyhow re-added rights and seems OK...
          Not sure how rights were lost, but that's another problem....!
