Description of problem:
The internet connection of one of our Galera nodes was severely degraded for around 30 minutes. The high (~90%) packet loss caused the node to lose synchronization with the rest of the cluster. After the internet connection was restored, the node stayed in the 'Joining: receiving State Transfer' state instead of catching up and synchronizing with the rest of the cluster.

Version-Release number of selected component (if applicable):
galera.x86_64 25.3.32-1.module+el8.3.0+10472+7adc332a

How reproducible:
Unknown.

Actual results:
I had to 'kill -9' the mysqld process (gracefully stopping the daemon didn't work). I could then start the mariadb service like normal, and the node successfully synced again.

Expected results:
The Galera node should successfully resync once connectivity has been restored. No manual intervention should be required.
