Hi,

We are plagued lately with an issue where bgpd terminates quite frequently out of the blue on one of our hosts. We weren't able to find anything in logs, but eventually strace gave us some information:

[pid 13589] 10:04:47.905970 write(2</dev/null<char 1:3>>, "bgpd: lib/zlog_targets.c:127: zlog_fd: Assertion `iovpos == 0' failed.\n", 71) = -1 EBADF (Bad file descriptor)

Searching Google only turned up this:
https://git.edevau.net/Ede_Vau/frr/commit/db2baed166581081db692fab0214752dbb121ed3

Looking at FRR's Github it looks like this has been fixed? If that is the case are there plans to release this fix and if so when could we expect to see a fixed version out?

For now we've increased the logging level to debug and currently monitoring to see if that's a viable mitigation. Are there any known mitigations we can try (if this doesn't work out)?

We are running FRR 7.5.1 on CentOS 7.

Kind regards
