Harmening from comment #22) Yesterday I grabbed 13.2-RELEASE/amd64 stock installation DVD image, created bhyve virtual machine installing 13.2 from the image, built custom kernel as GENERIC plus DIAGNOSTIC/INVARIANTS/WITNESS but without any patches. I tried to reproduce the problem with naive shell script: #!/bin/sh i=3D0 while : do i=3D$(($i+1)) case "$i" in *000) printf "%u\r" $i ;; esac killall -1 syslogd done 997000 iterations did not reproduce the problem. Either it does not present= in the release but only in stable/13, or the script is too haive. All I got is= a line printed to the console after its termination with Ctrl-C: Expensive timeout(9) function: 0xffffffff80c6a980(0xfffffe00093e6560) 0.417209440s --=20 You are receiving this mail because: You are the assignee for the bug.=
