Same problem here with Debian 12 and fldigi 4.1.23 (latest in the mainline repository).? Locks up every few days with high CPU utilization.
?
It's the program, rather than some RFI or other environmental.?? Been there, have the t-shirt.? Too predictable for that, plus the OS and other programs run rock solid.
?
My guess is a Pipewire incompatibility as mentioned.? Will be checking out the potential flmsg connection.
