Upgraded to 2.1.0, VM aborts about ever 30 min. -> Fixed in SVN

[ken newton]

Hello, I upgraded Virtual Box today to fix the NAT bug, and now the VM "aborts" constantly. Old version created a dump file in my home folder, doesn't anymore, attached is the most recent machine log.

Sigh. Could you read before you open a bug report? I don't know what we do wrong as people constantly doing cut'n'paste with log files although we clearly state that the users should not. There is a Attach button.

Regarding your problem: The VBox.log file looks like the VM crashes anyway. Please could you try to generate a ​core dump?

VBox.log by the original reporter

First, sorry for not attaching. Second, I tried to run the core dump, but was not successful. Can you provide instructions, or a link?

[ken newton]

I ran the command

$ ulimit -c unlimited $ /usr/lib/virtualbox/VirtualBox -startvm "Machine 1"

and got this

Segmentation fault

Please look ​here.

[ken newton]

Actually, I did. The only error I got was with

$ sudo echo -n 1 > /proc/sys/fs/suid_dumpable

I got a permission denied, even though I ran it with sudo

I tried the same VM on a 32bit 8.10 host, same abort.

[Frank Mehnert]

I've updated the ​instructions. Please could you try again with

sudo su
echo -n 1 > /proc/sys/fs/suid_dumpable
exit

?

Hi guys,

Ok, So i recently upgraded to 2.2.0, to get rid of the NAT bug, too. Now my VM segmentation faults several times a day, as opposed to the once a day on 1.6.X.

I'm on ubuntu hardy with a 64bit host, with a linux guest.

What can I do to help fix this bug?

Adam, any chance to send me a core dump? You can contact me at frank _dot_ mehnert _at_ sun _dot_ com and I can tell you an FTP server where you could upload the core dump if necessary.

[Frank Mehnert]

Adam, please check the latest release (2.2.2), it has fixed which might be related to your problem. If VBox still segfaults, please could you send me a core dump, see above?

Replying to newtonke:

Hello newtonke and Adam, What should I do to reproduce this crash?

[Frank Mehnert]

Adam already told me that he runs phpBBv3 in a VM with port forwarding. His VM crashes after 15-30 minutes. So accessing a web server running in a VM should do it.
