I am having a PHP web based application which is running on Apache 2.2. The issue is, if I put my application in to an idle state for some time the application is not responding after that. The idle time is varying for different time. Some time it get unresponsive in 15 mins, some time 30 min or 1 hour also like that. I think my Apache is not able to make the connection here after some time of inactivity. At the same time if I am trying to access the application from different client(system) it is working fine.
I am using persistent connection with DB but the sessions are under control DB side. Somebody please help me on this.
