Description
Hi,
first off, thanks for all the hard work - I can't count how many WireShark/npcap installs I've done over the last X years. It's appreciated.
Right now I'm working on a C# .net core app that will concurrently playback multiples PCAPs using packet queues. I'm using the latest nmap release with the latest master of SharpPCAP. I've got each playback in a separate thread (using the Task/async framework in C#).
Sometimes, it works fine. I have had instances where my tool was able to run 10 concurrent playbacks. But a lot of the time, I get an exception, right at start of playbacks. Please see the attached screenshot. It's weird that it's so intermittent.
Please let me know if you need any more data. I'll post up my read/playback method later today, if you think that'll help.
Thanks,
jason

Research direction
Start with the attached error screenshot and the report's concurrent C#/.NET Core playback setup. The promised read/playback method and additional exception details are not included, so gather a reproducible case for multiple concurrent PCAP playbacks before locating the failure. Done means the intermittent startup exception is reproduced, explained, and verified as resolved.
