[asterisk-users] Anyone ever experienced a crash where Asterisk debug output a line with all nulls

[Dan Cropp]

I have been told they went to an earlier snapshot of the VM and are running on that one now so we no longer have access to the VM from the state it was in.

The startup on their old snapshot VM is taking about 2 seconds for asterisk to load the configuration files.

Someone finally admitted to me the VM that crashed was missing over 200 package updates.  At this point, that's what we are chalking it up to.

Have a great day!

Dan

Well, it was just speculation. Is it even now reproducible after the 3. or even later reboot? I would try to log in via ssh as fast as possible (or directly via a shell) and try to find the responsible process. Try to examine the IO.

If the machine is shut down manually, did it perform a correct shutdown (= all file systems have been correctly unmounted and all processes have been stopped before unmounting)?

Is the startup slow even if it's done w/o reboot before?
