VM with Linux crashes worse than DOS or Windows 95. Your dog can crash it

[DanV]

Just write elementary program which creates large files, say, 1GB in size or one large file larger than 32 GB. And when your program running created 32GB of data in files VM part with Linux 100% crashes.

Or if you have already large files aaa1, aaa2... and you combine them into one large file bbb which will be larger than 32GB this will also crash VB with its Linux like it is a dumb DOS 2.1. Here is syntax how to do that.

$ ssh aaa* > bbb

I can try to attach this few lines Fortran program which is creating multiple files 1GB but if this will fail (because i do not see any links or buttons how attach the file) you also can take it from the Forum (Windows Host part) where i was just published it.

P.S. I failed to attach the file. OK here is the text. Just compile it with gFortran or any other Fortran compiler and run telling it to create more than 32 files (each will be 1 GB size file). It will crash at file #31

See the description how to compile in the text of the ticket. Or i can send you EXE if you want

In addition to not clear way how to attach the files I also can not edit/modify this ticket. Text became yellow in color and that's it, there is no any way to edit it.

Can you make your ticket system more user friendly???

I made a typo the combination should be

$ cat aaa* > bbb

Damn, lost one hour

[DanV]

Also remove the second attachment, i can not do that...jeeezzz

Holly .... The text of Fortran program became totally unreadable in your ticketing system...

Please attach a VBox.log of the affected VM.

@aeichner:

You can take the log file from the corresponding forum thread ​Critical error and freeze with 100% probability.

Wow, the host has 128GiB of RAM and the VM has 108GiB assigned. However he log says that only about 88GiB are available:

00:00:02.159631 Host RAM: 130973MB (127.9GB) total, 90954MB (88.8GB) available

Maybe you can check whether lowering the guest RAM helps to avoid that crash. It shouldn't crash for sure but this would narrow down the issue for us. Unfortunately I don't have system with that much RAM for testing available (I have one with that CPU though but it "only" has 64GiB of RAM).
