Hi,
We have 2 websites running one 1 app pool. Data flows between these 2 sites using web services. Over the last few weeks, we are facing intermittent issues wherein one of the site becomes inaccessible and after restarting IIS it does become accessible.
We are unable to reproduce this issue in our UAT or Dev environment. I ran the Debug Diagnostic Tool in Dev and found this message. I am trying to understand what could have wrong here.
In w3wp__xxxxx-TENANT-APP__PID__20444__Date__07_20_2017__Time_03_11_58PM__759__Second_Chance_Exception_E0434352.dmp the assembly instruction atKERNELBASE!RaiseException in C:\Windows\System32\KERNELBASE.dll fromMicrosoft Corporation has caused a CLR Exception on thread22 with the following error information:

Are these symptoms of any memory leak? Seeking support in troubleshooting this.
