Product: Base System
Version: 15.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---

To test this, I'm running on:
FreeBSD vr.home.dclg.ca 15.0-PRERELEASE FreeBSD 15.0-PRERELEASE #0
main-n279821-f13a042a5711: Tue Aug 26 18:50:10 EDT 2025
[email protected]:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG amd64
I run:
rpcbind -d
Then I run:
rpcinfo localhost
[2:25:325]root@vr:/vr1/backup/Acronis> rpcinfo localhost
rpcinfo: can't contact rpcbind: : RPC: Unable to receive; errno = Connection
reset by peer
coming back to rpcbind, it says:
[2:51:351]root@vr:~> rpcbind -d
rpcbind debugging enabled.
Segmentation fault (core dumped)
... so I:
[2:52:352]root@vr:~> gdb rpcbind rpcbind.core
