OS/2 session freezes or crashes

[Rafcio]

This is not limited to OS/2 clients, but it seems that Windows clients are far more resilient than OS/2 clients. The OS/2 client session either freezes (sometimes the mouse cursor still moves normally within client window, but sometimes it is not visible at all within client window), or crashes (the client reboots). I'm attaching all log files, because all sessions ended abnormally one way or another. Please analyze them all. There is no specific trigger. Quite often the client freezes on idle sessions. There was always some stability issues on this particular host machine, like I indicated concerning not only OS/2 clients. When this happens the host OS still works normally, but I suspect that there may be some incompatibility with the host configuration.

Please provide a minidump for the crashing VM.

Oops, another ticket that I didn't get an email with an update. Sorry for the late response. I don't think there is (can be) a minidump created for this issue. There is no pop up window with the typical message "Windows encountered an error... blah, blah, blah". The VM window stays up (well, gets smaller for the boot logo), but the guest reboots suddenly. Another symptom is that the guest freezes (stops responding) and the mouse cursor is not visible when within the guest window, so the VM has to be reset or closed. The VM itself doesn't crash, it's the client that crashes or freezes.

Please reopen if still relevant with a recent VirtualBox release.
