Hi, I'd like to provide some additional data on this problem.
I added some code into Equals method of System.MulticastDelegate that uses Object.ReferenceEquals(this,this.prev) to check whether this == this.prev, I used it instead of this.Equals(this.prev) because we suspected that original Equals method is responsible for generating stack overflow. When these references are equal I'm writing it into error log of apache2. So far without any success. After testing application with heavier load StackOverflow happens or entire application crashes ( when SO occured apache2 log looks like this: http://monobin.com/__f495ba429 ) I also managed to receive error page like this (I was trying to sign up into application after stack overflow without restarting the apache server): http://monobin.com/__f6f4607b3 We modified our application so we can use external session state provider, but it didn't help. From our observations we can tell that if we are using asp-state2 for session data the stack overflow is likely to appear and if we change it into in-procces mode whole application crashes. The weird thing is that under light load everything works fine, so it looks like under heavy load all session data magically disapear. This is the lead we will try to investigate now. This behaviour occurs on mono 2.10.1 compiled from tarball. This week I'll try to switch it to 2.10.2 and if anything changes I'll let You know. I can provide more data/logs if needed Thanks in advance for any piece of advice Best Regards, Pawel krlm wrote: > > Hello, > > I've found an issue in my ASP.NET application when it's running under > heavy load.
