We occasionally see that a verto user loses access to a conference for ~15 seconds. Here's an example from our FS v10.5 / Debian-Buster logging. Note the BAD READ which seems to be the cause:---------------------------------------------------------

---------------------------------------------------------
My understanding of BAD READ is that it usually indicates an incorrectly-created or expired cert, but this BAD READ is happening after the DTLS handshake was completed.
Do you have any recommendation for how we can avoid such BAD READ's? |
