      Things were working great for the past day or so - I guess it was too good to be true!  I was checking a site when the web performance went to horrible/non-responsive.  The CPU on the polling/web server is pegged and I noticed the businesslayerhost process crashed again.  I had to restart the SolarWinds Orion Module Engine service and since this is how thing are - not responsive again.  Do I need to restart all of the services again?

      We are running NPM 9.5, SP4; MSSQL 2005 enterprise on a seperate server.
