On booting 1.3.0 (epa3), I saw something I never saw before at boot time:
vyos@gw# sudo journalctl|grep -i frr Nov 13 13:58:30 gw vyos-router[745]: 2021/11/13 13:58:30 WATCHFRR: failed to mkdir "/var/tmp/frr/watchfrr.889": File exists Nov 13 13:58:30 gw vyos-router[745]: 2021/11/13 13:58:30 WATCHFRR: crashlog and per-thread log buffering unavailable!
Upon checking /var/tmp/frr indeed there were directories left behind for old watchfrr processes:
vyos@gw:/$ sudo ls -la /var/tmp/frr total 88 drwx------ 22 frr frr 4096 Nov 19 15:07 . drwxrwxrwt 1 root root 4096 Nov 21 00:00 .. drwx------ 2 frr frr 4096 Nov 19 15:07 bfdd.982 drwx------ 2 frr frr 4096 Nov 19 15:07 bgpd.946 drwx------ 2 frr frr 4096 Nov 19 15:07 isisd.967 drwx------ 2 frr frr 4096 Nov 19 15:07 ldpd.971 drwx------ 2 frr frr 4096 Nov 19 15:07 ldpd.972 drwx------ 2 frr frr 4096 Nov 19 15:07 ldpd.973 drwx------ 2 frr frr 4096 Nov 19 15:07 ospf6d.965 drwx------ 2 frr frr 4096 Nov 19 15:07 ospfd.961 drwx------ 2 frr frr 4096 Nov 19 15:07 ripd.956 drwx------ 2 frr frr 4096 Nov 19 15:07 ripngd.958 drwx------ 2 frr frr 4096 Nov 19 15:07 staticd.977 drwx------ 2 root root 4096 Nov 13 13:58 watchfrr.907 drwx------ 2 root root 4096 Nov 13 10:08 watchfrr.21842 drwx------ 2 root root 4096 Nov 13 9:24 watchfrr.889 drwx------ 2 root root 4096 Nov 19 15:07 watchfrr.900 drwx------ 2 root root 4096 Nov 14 13:30 watchfrr.905 drwx------ 2 root root 4096 Nov 14 13:20 watchfrr.906 drwx------ 2 root root 4096 Nov 15 09:04 watchfrr.909 drwx------ 2 root root 4096 Nov 19 13:53 watchfrr.914 drwx------ 2 frr frr 4096 Nov 19 15:07 zebra.937
However improbable, the PID seemed to have clashed with an old and earlier invocation of the watchfrr process. What are the odds...
