IIS 7.5: problem with Application pool

application-pooliis-7

several time in day my Application pool is stopped with following error:

Application pool 'MyApplicationPool'
is being automatically disabled due to
a series of failures in the
process(es) serving that application
pool.

How to resolve this?

thanks, for the any advice.

This is because your application pool is crashing more than 5 times in 5 minutes [default settings - Rapid Fail]

Instead of disabling Rapid Fail, you should consider taking Crash Dumps and try to find out the root cause. http://blogs.msdn.com/b/rahulso/archive/2006/03/02/what-is-a-crash-technically-in-asp-net-and-what-to-do-if-it-happens.aspx
