I'm running BackupPC to back up my debian clients (all on trixie), after
updating the clients to 3.4.1+ds1-5+deb13u4 the rsync process
consitently froze in the middle of the jobs without anything suspicious
visible with strace. (both sides in pselect timeouts + occasional
keep-alives sent over the tcp connection)

Manually installing 3.4.4+ds1-1 from forky on one client led to a
successful backup job.

Please update the stable Debian package to the new upstream version.

Thanks,
