Hi Samir Vaidya,
It seems that your application pool is recycled very often. When you open some pages it might be the case that you also wait for the startup routines of sitefinity - and it is even possible that you get several restarts in a few minutes. The problem is that currently sitefinity is pretty much a memory-hungry application(it can very quickly reach 500mb) and your hosting plan - most probably has memory restriction after which it recycles the pool. One solution is to host on a better plan - like semi-dedicated or dedicated server - and not to have such memory restrictions. In the next Q we are going to focus on optimizing and decreasing the memory footprint of sitefinity.
