 We recently tracked down some issues with the pion library that were
 causing inefficiencies and infinite loops to occur (see #33211).

 These have been addressed in pion-dtls `v2.0.0-rc.7` and pion-sctp
 `v1.7.5`. I'd suggest just bumping to the latest version of pion-webrtc
 `v2.2.3`, which includes version bumps for each of these supporting
 libraries.
