InvalidOperationException in SaeaLayerCallback

[thelalle]

I got this exception and it caused my app to fail.

Exception Info: System.InvalidOperationException
Stack:
at Nowin.SaeaLayerCallback.StartReceive(Byte[], Int32, Int32)
at System.Net.Sockets.SocketAsyncEventArgs.FinishOperationSuccess(System.Net.Sockets.SocketError, Int32, System.Net.Sockets.SocketFlags)
at System.Net.Sockets.SocketAsyncEventArgs.CompletionPortCallback(UInt32, UInt32, System.Threading.NativeOverlapped_)
at System.Threading.IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped)

Sorry for not have more information i got that from the event log, the app segfaulted after that.

StartReceive could throw such Exception, but that callstack is completely strange. You probably cannot reproduce it?

[thelalle]

I cant reproduce but it reproduces itself like once per day. Have to change to the stupied httplistener :'(

[Bobris]

Ok, I will think how to attack such problem. Would you be able to to run some version with enhanced debugging?

[thelalle]

Sure thing

[Bobris]

Do you use https or just http?

[Bobris]

Also do you have nowin.pdb? I still thinking why that callstack could be so illogical.

[thelalle]

Just http. Its from nuget.

I am publishing also symbols for every version. You can just follow this http://www.symbolsource.org/Public/Home/VisualStudio to setup their download.
And then just run it under debugger, or attach debugger.

[Bobris]

Just info. I think I fixed this bug in latest version, or at least I tried. If you will find this again, please report.

Just in case you already get to it, please update to even better version from today.

For last two commits (delayed accept) I seem to be unable to find code that actually sets this (DelayedAccept) flag in saea.

[Bobris]

Good catch, thanks a lot. It should be in ProcessDisconnect(). I will fix it later.

[Bobris]

Fixed. Thanks again for code review.
