Comment	> Ping requests are quite heavy resource demanding tasks for a web > server. In addition, those requests have a very long lasting live, > compared to any other web server request. > > Current Activesync code has no limit to the number of Ping requests a > server is going to attend for a single user/device. One of my devices > (Android phone) had some issue that made it fire a Ping request every > few seconds, so the server ended up trying to fulfill more than 90 > concurrent Ping requests, which degraded whole server performance. It > shouldn't be a problem if those requests weren't so long lasting. > > I think there's no point in attending more than 2 or 3 concurrent > Ping requests for a single user/device, beyond dealing with mobile > devices when switching between wireless connections. Right now an > error on a single device can freeze a nice production server in just > a few minutes.
