Hi all, We just upgraded from freeRADIUS 1.1.7 to 2.1.10, and we're having issues getting freeRADIUS to work with a thread pool (see debug logs below). The thread pool config was working in version 1.1.7. Were there major changes on how threads were implemented from 1.1.7 to 2.1.10? Why might we be having this issue? Debug log with thread pool:
