IIS 7.5 - Website needs restarting every morning

I have an Umbraco website that I have to restart every morning in order for the users to be able to publish content. Is there 开发者_开发技巧any solutions available that will help me get around doing this each morning?

1 - Document why do you "have to" restart IIS every morning

• like the web app can't re-establish connection with SQL
• or one process gets so huge that it's obvious it's leaking
• or one process heats up with huge CPU usage and IIS keeps dropping requests
• etc. etc. have to check log files, EventLog, SQL Server has it's own log

2 - Document usage patters of the site

• like does it sit idle for 8-10 h or is busy all night
  • if it's busy then log files (including IIS log) will provide some info on when a problem started
  • if it's idle for a long time, check that AppPool for the site has automatic recycling of worker process set say after 1h of inactivity - you can also set diferent recycling tactics
  • if it's SQL connection after along idle period - Kerberos ticket for the account expired.
    • you do have a domain account under which that AppPool runs I hope
  • to fix that, look at DB connection string (normally in web.config) and check MSDN for params
  • or bring up a new web site or app that's going to keep pinging a web method which will just do a little query ( like a count on some table) and return the result as a kind of admin heartbeat -- this helps only if you acsually see SQL connection issue

3 - Check if you have multiple sites / web apps running on the server

• that each has it's own AppPool and that they run under a domain account
• that each app has it's own, separate folder for logs and any other writable files
• that each AppPool has recycling tactics that's good for actual usage pattern
• needs different recycling tactics if it's busy all the time
• ask sor some mininal kind of heartbeat web service to be developed and pinged for ops needs
  • running as part of each web app and using the same SQL connection
  • if you don't have the budget for this raise some hell
    • makes you feel good :-)
