Every day, between 2:30 and 3:30 pm, several of our Domino servers on different AS/400s page out that the server response is slow (response to access to names.nsf takes longer than 90 secs). We can not find any agents or tasks that are running at this time, other than the normal server tasks. This just started happening (have not done any upgrades recently). Users that are in their mailfiles, see a significant decrease in performance, and those getting into their mailfiles, see "server not responding". The only thing we see is that the HTTP process is taking about 40 - 55% of the CPU utilization. We have been working with Lotus and have now escalated this to a critical incident. Has anyone else seen anything like this?
