Tinc node is crashing after some days or weeks. How to debug?
Hi I have not tried systemd-coredump yet but I found something strange in my syslog file. Like this message in the en of the log file: tincd[10322]: segfault at 7fffb3180000 ip 00007ff7937f11c2 sp 00007fffb317dd68 error 4 in libc-2.23.so[7ff7936a3000+1c0000] There is more in the attached syslog file. Any clues?

Usually dont respond. But you have been waiting. And it seems simple. According to your vpn log. A computer is "in the future". Insure your 2 nodes are on the correct time. Honestly. One node being to far in the future... breaks things. Try that.
