Is there any known issue which will cause this problem? Or do you have any
suggestion on how to debug?
As written in the report, it looks like dbus-daemon or PID1 itself not
responding. Some insights may be obtained by looking at /proc/1/stack
and /proc/$pid_of_dbus/stack (as root).
Hi Michal,
The issue happened again, but the /proc/1/stack and
/proc/$pid_of_dbus-broker/stack are both empty on our platform.
I checked kernel config and confirmed that CONFIG_STACKTRACE is enabled:
zcat /proc/config.gz | grep CONFIG_STACKTRACE
CONFIG_STACKTRACE_SUPPORT=y
# CONFIG_STACKTRACE_BUILD_ID is not set
CONFIG_STACKTRACE=y
Is there any other config that is missing?
Thanks,
Heyi
HTH,
Michal
