Would you be able to provide the scenarios that can be replicated that lead to stack overflow?

@DanielDignam As @budgetpreneur requests, please let us know which version you pulled, and how to reproduce this issue.

We pulled 3.4.0.1, there recursive error recovery appears to sill be there in 3.4.0.2. Unfortunately, I don't have a simple reproducible case.
The error condition arose for us on a machine restoring from hibernate state. We would get an error 'cascade'

I managed to get the process in the act of dying in the debugger and it was a stack overflow thru the excpetion handling MultiChannelSubscribeRequest. Which, I think, is what you would ultimately expect?
It might have been that it took several restore from hibernates to get there. The first restore will chew its way thru several recursion levels, and the network will become available, and it will work. User closes lid, and then on the next restore we recurse several more levels. It was also quite hard to repro. I never saw it in a VM environment, or using a BootCamp'd MacBook. I saw it after a couple of days on a Dell. So there is a a bit of guesswork, and basically removing the obvious 'error' when I hit it, rather than building a reproducible test case.
Apologises for the lack of precision,
Is there a test which randomly drop the network, maybe I can reproduce it by modifying one of those ..

Also, there are suspend fixes in 3.5, correct @budgetpreneur ?

There is some attempt at power management in 3.4.0.1 I believe

@DanielDignam
In PubNub 3.5, we have refactored code to improve machine suspend/awake feature. It will be released soon to NuGet along with new features PAM grant, audit.
In 3.5 example code, option 19 and 20 will enable us the simulation of machine sleep/awake modes; options 10 and 11 will enable us to enable/disable network simulation.
BTW...please let us know the environment(OS, .net framework) of your test.
You can also send email to PubNub Support for assistance.

@budgetpreneur in the meantime, @DanielDignam can test from here: https://github.com/pubnub/c-sharp/tree/master/csharp.net/3.5 , correct?

I've duplicated the issue. It's actually triggering when we go into suspend, maybe a race condition between receiving the suspend event and the network connection actually being powered down?
From the logfile I have this sequence, note we report (GrabCAD) report entering suspend, pubnub gets an exception, and then reports the entering suspend. The socket exception and webexception are what cascade the stack overflow.

@DanielDignam ,
Would you mind to let us know the machine environment like OS, .net framework version.
In your original post, you indicated "..replaced it in our app with a simple loop, and the chap seeing the error has reported no more problems". Do you mind to share that simple loop logic which you reported "no more problems". I would like to see if there will be any impact or side-effects, before I incorporate it in our next release.
Thanking you.

I duplicated the issue on a Dell XPS 13 running Windows 8.1, the application is running against .NET 3.5, report came from a Dell running Windows 7, we're using 3.4.0.1.
I'm guessing I should put a pull request together ?
I'm looking into it some more, the stack I posted above would not be fixed by my change,

@DanielDignam
I would recommend you try the version from https://github.com/pubnub/c-sharp/tree/master/csharp.net/3.5, which is much improved than 3.4.0.1. You can also try unlisted NuGet pre-release version 3.5.0.1-rc6 by executing the following command in your package manager console.
Install-Package Pubnub -Version 3.5.0.1-rc6 -Pre
Please let us know how 3.5 from Git or Nuget 3.5.0.1-rc6 behaved on your win 8.1 machine.

commented on September 8, 2024
@DanielDignam ,
TerminatePendingWebRequest(RequestState state) expects null value to terminate any pending subscribe/presence requests. So when state = null, we run else part of the if condition. Basically when state = null, we are retrieving key collection and terminating any available pending pubnub web requests. Could you be more specific where null reference exception was raised because I did not see null reference exception in the provided log. Also please let me know if you still notice "stack overflow" with 3.5 when machine goes to suspend mode.
from c-sharp.
DanielDignam
commented on September 8, 2024
If there is a currentRequest isn't a null reference exception pretty much guaranteed if state is null. We will take the else, and then try and access state.ErrorCallback ? That was were I saw the exception
private void TerminatePendingWebRequest()
{
TerminatePendingWebRequest<object>(null);
}
private void TerminatePendingWebRequest<T>(RequestState<T> state)
{
if (state != null && state.Request != null)
{
...
}
else
{
ICollection<string> keyCollection = _channelRequest.Keys;
foreach (string key in keyCollection)
{
PubnubWebRequest currentRequest = _channelRequest[key];
if (currentRequest != null)
{
TerminatePendingWebRequest(currentRequest, state.ErrorCallback);
}
}
}

Thank you for your input.
Fix was made to handle null and it is available at https://github.com/pubnub/c-sharp/blob/PN-513/csharp.net/3.5/PubNub-Messaging/Pubnub.cs#L647.
You can get fix from branch PN-513 or replace "state.ErrorCallback" in line# 647 with null.
We will release to master as soon as possible.
Also can you please confirm if stack overflow issue is resolved or not.
