Connection freezes and promiscuous mode enabled / disabled : again and again

[Rajstopy]

Dear all,

This is a desperate call for help because I'm now struggling for months with disconnection issues, happening randomly on OPNSense.

My setup :
PowerEdge R240 - ESXi 6.7 and OPNSense 21.1 running in a VM.

Everything worked smoothly for months and the first issue happened since version 20.7.
I do experience random network disconnection. When this happens, OPNSense interfaces becomes totally unresponsive, but access to console remains possible.
I've checked for logs, but nothing really significant neither on ESXi side, nor in OPNSense. The only thing correlated with this frozen state, is a bunch of pflog0: promiscuous mode enabled / disabled in OPNSense log file. Sometimes hundreds of entries, looks like if something is looping.

I don't know how / what investigate further and this issue just makes me crazy.

Just thinking about switching to pfSense to see if this issue still remains.

I've seen dozen of similar issues in this forum, but never seen any outcome / resolution.

Any help would be really appreciated.

Cheers

hi

I do experience random network disconnection

why?

Hi there!

Obviously my post is confusing I do apologize.

When I say I lost the connection, that's due to the fact OPNSense becomes unresponsive.

Digging a little bit in ESXi log file, I found the following strange message happening from time to time, related to the VM linked to OPNSense

Code: [Select]

2021-02-12T18:32:47.919Z| vmx| I125: Destroying virtual dev for scsi0:0 vscsi=8336
2021-02-12T18:32:47.919Z| vmx| I125: VMMon_VSCSIStopVports: No such target on adapter
I didn't found yet is this may be a root cause.

Just thinking about my underlaying VMWare infrastructure rather than a faulty OPNSense...

Hi, I have very similar problems right now. We also use ESXi 6.7 and have at least 2 "breaks" every day in the morning and evening for about 10 to 20 minutes. After that it continues without reboot as if nothing happened. In the logs I haven't found anything unusual yet. Could you solve the problem in the meantime?

Many thanks & greetings
