Since the patch doesn't stop the crashes, that suggests that it isn't just a socket refcnt problem. Can you give us everything you can think of related to your network configuration. (We now have three people reporting this, but we do not know what is common between them that is causing this.) Note that this krpc code has not changed in at least a decade, so I cannot see how the bug could be in the krpc code. --> All we seem to know is that it was introduced in FreeBSD 15. --=20 You are receiving this mail because: You are the assignee for the bug.=
