Segmentation fault with Windows 10 guest, VB 6.1.0, Solaris 11.4 SRU 21

Post by bmccrary »

I've just started running Virtualbox 6.1.0 on a Sun Netra X4270 with Solaris 11.4 SRU 21. I'm running Windows 10 guest and connecting using rdesktop. I've used Virtualbox for years and never had this kind of problem, but it just randomly has a segmentation fault and dies. It doesn't seem to matter what the guest OS is doing. The only think different I'm doing this time is using RDP and rdesktop to connect to it and running the VM through the VBoxHeadless command. I looked through the logs but there's no mention of anything when it crashes, it looks normal up until then. Anyone know of anything I might could try to do to isolate the problem?

After running a VM over the weekend with a stress tester on the guest OS, I think the problem is simply the VRDE server built into VirtualBox. Disabling that has seemed to cure the segfaults. It usually wouldn't run over an hour before. I just setup RDP on the guest itself, now that it's installed, and I'm good it looks like. Just FYI if anyone else runs into this.

Could you file a bug using https://www.virtualbox.org/wiki/Bugtracker ->
Create a new bug ticket and include the details you supplied here along
with a stack trace of the crashed VM? There should be a crash of the
VirtualBoxVM process in /var/cores (you can double-check the core file
configuration using coreadm(8)) and then using mdb(1) against the core
you can run '$G ; $C' to first enable C++ symbol demangling and then to
get a stack trace of the thread which crashed. Thanks!
