crash in VB 3.0.0: VBoxREM.so

[Stéphane Charette]

VB 3.0.0, both host and guest are Ubuntu 9.04 64-bit.

After several hours of use, my guest window crashes. Complete crash, where the window disappears and nothing about the crash is logged to VBox.log.

In the host, the following is logged to dmesg:

[286059.813502] VirtualBox[1000]: segfault at 0 ip 00007ffc0b8089f0 sp 00007ffc0b262d70 error 4 in VBoxREM.so[7ffc0b7f6000+7a000]

You'd better mentioned that use 4 vCPU guest config. Guest SMP is still experimental and WIP. Do you see the same problem in 1 vCPU config?

... and does anything change with VBox 3.0.2?

[Frank Mehnert]

I assume this is fixed as there was no response for 2 month.

I'm experiencing this problem:

• Host operating system: Ubuntu Desktop 9.04 x64
• Guest operating system: Ubuntu Server 9.04 x64
• VirtualBox 3.0.10 r549097

Yesterday my machine auto-updated to a new version of VirtualBox, the guest server has died twice since then.

From /var/log/syslog:

Nov 3 12:35:12 alex-pc1 kernel: [1039134.249546] VBoxHeadless[15220]: segfault at ffffffff ip 00007f46d27c4595 sp 00007f46d23ecec0 error 4 in VBoxREM.so[7f46d27b8000+7a000]

startup log of the virtual machine that died

A core dump would be very helpful.

[Alex Black]

I don't think it created one yet. I read up on this: ​http://www.virtualbox.org/wiki/Core_dump and hopefully it will dump core next time it crashes. I imagine the core dump will be huge though.

[Frank Mehnert]

If you can provide a core dump please contact me via frank _dot_ mehnert _at_ sun _dot_ com. I can tell you a server where you can upload the file.

[Frank Mehnert]

Still relevant with VBox 3.1.4?

[Stéphane Charette]

As the OP, I don't think I've seen this since the 3.0.0 days in July 2009.

[Frank Mehnert]

Thanks. Others in this ticket: Please reopen if necessary. In that case please contact me for providing a core dump.
