Normally my Solarwinds Core Server CPU usage is about 40-60%. Last week after I created about 40 empty groups, the CPU usage is keeping at 100% constantly. “Solarwinds Information Service V3” is using most of CPU power (always above 60%). After I removed the groups, system is back to normal.
Found the cause but not sure why? Any idea? Or a bug in SolarWinds?
Thanks for any help!
