    ePO server CPU spikes

      Strange behaviour this.  It would appear that we're getting 100% cpu spikes every minute on our ePO server. I have no idea what would be causing this, but the most frequently a server task runs is every 30 minutes.  The server.log file is full of entries referencing HIPS policies, but we're not using HIPS, only VirusScan and some EEPC 6 and Host DLP clients.

       

      entries in the server log appear to be like this:

      Any thoughts?

       

      Thanks

          If you're not using HIPs, I'd suggest removing the HIPs extension. I know that there are some background tasks for HIPs that can cause issues - if you don't need it, try removing it

            Thanks Joe.

             

            I'll let you know how we get on.

              Hi Joe,

               

              it looks like removing the HIPS extension has helped somewhat although we're still monitoring the server performance.

               

               

              One of the guys asked if there would be any advantage to removing other unused extensions (such as Groupshield for Lotus Domino, LinuxShield, RSD, Spamkiler) since the HIPS one seems to have had a positive effect.  Do you reckon it'll help or is it just the known background tasks for HIPS that cause the problem?

               

              Thanks

                By all means remove extensions for things you're not using - if nothing else it makes things a bit neater

                RSD has a lot going on in the background - the others don't, as far as I know, but removing them may have a small effect.

                 

                As an aside, though, if you're hitting performance problems like this, I would very strongly recommend some database maintenance if it hasn't been done recently: in particular, a reindex, which can have an almost magical effect in some cases

                 

                Regards -

                  Are any database maintenance instructions available online?

                    Sure - try KB 67184 as a starting point

                        Joe,

                         

                        we're still hitting some severe CPU spikes on the ePO server despite a successful re-index of the database.

                         

                        All the unused extensions have been removed now, but they've not made much of a difference.

                         

                        We've run our performance monitor on the ePO server which has indicated that the increase in CPU utilisation coincides with an increase in open ePO Agent Connections. It seems to me that this is to be expected, and testing an amended Agent policy to increase the delay for Agent-Server communication from 60 minutes to 180 minutes and has reduced the CPU load by almost 20%.

                         

                        Would I be right in thinking that the box simply can't handle the number of clients communicating with it? What would be the best bet to deal with this?

                         

                        Cheers

                          Quite possibly, given what you've already said. What spec is the box? How many clients?

                           

                          Thanks -
