Bug ID: 233837
Summary: gcore on stopped process causes reboot...
Product: Base System
Version: 11.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
While trying to debug a Samba problem I wanted to grab core-dumps of running
winbindd processes, I then noticed that (as root) giving these commands:
# kill -STOP 49049
# gcore -c /var/cores/winbindd.49049 49049
causes FreeBSD 11.2-RELEASE-p5 to reboot immediately. Tried it on two different
systems (one old HP D380 G5 and a new Dell PowerEdge R730xd).
I think the "-s" flag to gcore also causes this effect.
