Hi Folks,
I'm really hoping someone might have some insight here. I am running a CentoOS 5 guest on my Mac configured with NAT. VB is forwarding two ports to it: SSH (222->22) and a custom port to access my server program (9010 -> 9003). All works nicely until I start pushing it a bit harder with requests (I run jMeter on the host to perf test the server program, using about 5 threads), at which point the networking to the VM stops working, my SSH connections timeout and I can't ssh in anymore. The VM stays active and I can log in to it fine through the VB console. I tried checking various system logs on the guest and host, VB logs. Heck, I even tried increasing the number of per process open files on OS X (in case I'm running out of sockets) -- no luck. Any ideas? How can I at least diagnose what the problem is?
VirtualBox 4.1.8
OS X 10.6.8
CentOS 5.7
