LockRecursionException in ThreadSafeList when disconnecting

[ianrandell-sh]

Hi there - first of all thanks for these brilliant libraries.

I'm getting the following exception when disconnecting as part of handling a connection error (a 403:denied_by_security_policy:create_denied in my case since the channel doesn't exist):

System.Threading.LockRecursionException

"Recursive read lock acquisitions not allowed in this mode"

What I'm using:

• a slightly modified version of ResilientStreamingClient from your CometD.NetCore.Salesforce repo
• version 2.0.6 of this nuget (v2.0.7 looks like no code changes)
• .net core 3.1 on Windows 10

My Disconnect() method in my ResilientStreamingClient is unchanged from your repo version.

Any help appreciated. I'll continue troubleshooting

Hmm.. this was a while ago but from memory I rewrote some of the code myself. Sorry I cant be more specific. I don't remember there being a very simple fix.

The problem can be fixed by enabling the READ permission in Salesforce, on the user profile name for which you want to assign permissions.

Thanks @toojannarong that solved the problem for me but I think the behaviour in this scenario is less than ideal, definitely room to improve how it's handled
