描述
I was able to reproduce a vboxsf crash twice whilst running "npm install" on a shared directory, which triggers a lot of different file activity (create/link/read/syay etc).
My guest machine is; Linux vagrant-ubuntu-trusty-64 3.13.0-49-generic #83-Ubuntu SMP Fri Apr 10 20:11:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 14.04.2 LTS
My host machine is; VirtualBox 4.3.24 on OS X Yosemite 10.10.2
Here is the dmesg;
