We have 3 SharePoint Front ends server and I can access top level site and other site collections. But there is 1 SharePoint subsite that I cant access from central administration and also if any users tries to access the page it loads and loads without any result finally shows page cant be displayed.
Any reason why this is happening only to one subsite? The site was working from last 1 year all of sudden I have seen this problem. Any thoughts would be appreciated.
If I do IISreset page loads but after some time it goes to same problem. I am not sure where the problem lies and how can I trouble shoot this issue??
Update URL for the subsite looks like below abc.com/DEF/FRA/FRACalendar
Problem looks with the list as other parts of sites loads without any problem. List has around 1400 items, we have event receivers on this list and timer job as well which would send an email to users when task is due.
When timer job runs and sends an email URL in body of the email will look like below. It takes lot of time when user clicks on the link. abc.com/DEF/FRA/FRACalendar/Lists/FRA%20Calendar/DispForm.aspx?ID=1637.
And also, Sub site loads in server, once I do iis reset.
