https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218653 Kaho Toshikazu <kaho@elam.kais.kyoto-u.ac.jp> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kaho@elam.kais.kyoto-u.ac.j | |p --- Comment #3 from Kaho Toshikazu <kaho@elam.kais.kyoto-u.ac.jp> --- (In reply to nn from comment #1) I think the link drop itself is caused by a Tx error, but you have many Rx errors shown by the Ierrs of the netstat output and you should investigate what errors occur at first. Can you see a `sysctl dev.em.0` result? Can you get which knobs related errors are increasing their counters?=20 For example, does rx_overrun or crc_errs has a non-zero value? --=20 You are receiving this mail because: You are the assignee for the bug.=
