MBUF rising steadilly using vmxnet2 NIC
- 
 I am using the VMware tools from VMware. The ESXi server is fully patched to the latest version and the tools are also at the latest version for ESX 4.one 
- 
 Anyone care to take a stab at this? I cannot use this solution if i cannot solve this problem. 
- 
 Does it show the same behaviour if you use an E1000 or VMXNET3 NIC? 
- 
 I'll clone the machine and switch it over to e1000. However, the CPU usage will go up significantly as a result. Lets see 
- 
 There are some docs online about how to get VMXNET3 working with FreeBSD 8.3, but I've never tried and don't know if pfSense would pick the cards up or not. 
- 
 Please remember that this is VMXNET2 on ESXi 4.1u3. Which isn't capable of vmxnet3. 
- 
 Sorry, I didn't remember. I moved off of 4.x a while ago. 
- 
 That's fine, I just wanted to ensure your suggestions are relevant to my issue.

 I guess it's possible the problem would be resolved on a more recent 5.x Vmware release. Are you tied to 4.x? Why not upgrade to the latest? I did test your scenario with native Vmware tools (Vmxnet3) on 5.5 and didn't have mBuf problems. I did have Mbuf problems with vmxnet2 on 5.1 and 5.5 when using openVMtools … I didn't try Vmxnet2 with 5.1 or 5.5 (native Vmware tools). I'm using Vt-d right now , so no longer able to test vmx NICs.

 The equipment I'm using as stated above is a Proliant DL360 G4p. the highest ESXi version is can run is 4.1u3.
