PFSense crashes with page fault/kernel panic on VMWare
-
Usually random instability on VMWare is from:
- Running an outdated version of ESX incompatible with the base OS
-OR, more likely: - The VM is using an outdated VM Hardware version. Shut down the VM and upgrade the compatibility level to match the latest available, then start it again.
- Running an outdated version of ESX incompatible with the base OS

Hi Steve,
Thanks for the post.
This was the first crash with this machine (let's call it VPN3-server) after updating PfSense to version 2.4.5-RELEASE-p1. I updated a machine just in the hope of solving an unexpected crash and reboot problem that occurred with that machine and another identical machine, also a VPN server (VPN4-server).
If you think it's relevant, I can try to recover information from the previous crash of the other machine (VPN4-Server). Information from the VPN3-server machine, unfortunately I didn't save it. Do you think it's important? Do you have anything specific that you would like me to recover from the previous crash? -
@Frogg said in PFSense crashes with page fault/kernel panic on VMWare:
I had something similar on VMWare 6.5, VM was crashing randomly between some mins and some hours.
It was a bug on the virtual network drivers:
Try to change the driver VMXNET3 by your network card in your VM network configuration
I hope it will solve your trouble.Hi Frogg,
Thanks for the tip, I'll keep this trick up my sleeve ;-)
But initially, I intended to keep the paravirtualized driver for performance reasons.Thank you.

Hi Jimp,
Thanks for the post.
Your hypotheses are interesting, let's explore them.
I talked to the virtualization infrastructure team and I have some answers:Our version of VMWare is ESXi, 6.0.0, 5050593, it's not really up to date, but I didn't think that was a problem.
The hardware version of the virtual machine is 11, the last available for that version of VMWare. The configuration template used by VMWare was āGeneric FreeBSD-64-Bitsā
The NIC is paravirtualized (VMXNET 3)
The current disk controller is the scsi āLSI Logic Parallelā. Do you think VMWare's paravirtualized alternative would be compatible and more appropriate?Jimp, the hypothesis of configuration problems in the virtualization environment is interesting, but there is a situation that contradicts this possibility:
I have another virtual PFSense with identical virtualization settings and version of PfSense that does not have this problem. Its function is only FW / GW of the wireless network and does not run VPN services. This machine has recorded almost a year of uptime in the same virtualization environment as the VPN servers that had an unexpected crash and reboot.

FreeBSD 11.x is not supported by ESX 6.0, see https://www.vmware.com/resources/compatibility/search.php?deviceCategory=software&details=1&operatingSystems=232&productNames=15&page=1&display_interval=10&sortColumn=Partner&sortOrder=Asc&testConfig=16
And ESX 6.0 is not "not really up to date", it's ancient in terms of ESX versions. It was released over 5 years ago and went EOL over 6 months ago.
Update your ESX version.

I know this post is about 6.5 and not 6.0 but maybe you can find this intersting:

Hi Steve,

Ok, that's pretty generic. No way to pin down stuff in netisr_dispatch really.
The thing to check is if other crashes have the same or very similar backtraces and panic strings.
However, and JimP said, ESXi 6.0 does't support FreeBSD 11 and hence pfSense 2.4. You really need to get that upgraded before doing anything else.
Steve
