Bus Error (coredump)
Hi, Knot, tag: v3.3.3 coredump with bus error, when reload. Can anyone help me troubleshoot?
I developed a personal module based on v3.3.3 without modifying the code in libknot.
I stress test the knotd with 5 process.
- knotd process
- watch -n 1 knotc reload
- dnsperf -m tcp
- dnsperf -m udp
- python script to change config every few seconds
then knotd and knotc failed in the same line, but the time of crash is not same.
