Approximately once every hour the system log indicates that the "application started". The restart occurs even if there is no traffic for an hour and also restarts if there is a customer actively using the store at the time of the restart. The site becomes non-responsive for several minutes while it is reloaded.
I assume this is because IIS is getting cycled and the cache is cleared and the site must be reloaded. I have contacted the ISP and they claim they have reviewed the server logs and it is not cycling IIS.
The site ran fine for several weeks and just started this even though no changes were made to the site.
What does "application started" indicate? Has anyone else experienced this issue? I am running version 3.8 in a plesk environment.
Thank you in advance.
