Hi, developers, thank you for your checking. I found a possible bug in UltraGrid, which locates in EmbeddableWebServer. It seems the lock server is not released correctly when!server->initialize in the function serverStop?

https://github.com/CESNET/UltraGrid/blob/e3c926c8ff67586bf74c4cc0763a78c83ede9cf6/src/EmbeddableWebServer.h#L1515-L1526 Can you confirm this?

The original issue: https://github.com/CESNET/UltraGrid/issues/183

My problem has been resolved.

Oh that certainly does look extremely suspicious! Thank you for reporting it
