Description

Hi,

I have a freenas NFS share mount on a linux machine.

Everything works well until there is high load (traffic/cpu).

For an unknown reason, i loose network connectivity to the freenas (all the jails also unreachable) and the only way to restore is with a hard reboot

Same behavior on the STABLE train, i've try the nithly release and same issue.

i had only 10gb of ram, i've boosted the machine to 16gb of ram, seems to have the same issue.

Thanks,
Louis

Why are you running MASTER instead of STABLE? It is not meant for production use and can be in a state of brokenness at any point in time.

Also, Realtek cards are known to be flaky and are not recommended.

Does running STABLE and installing an Intel card resolve the issue?

Thanks for the fast reply.

The same behaviour was happening with the STABLE release, I've changed to the MASTER last week to see if the behaviour will change but it's the same.

is there a way to pinpoint the problem to the Realtek adaptor? i haven't seen anything in the logs.today

Cant put an intel NiC on this machine (no physical space)

Thanks,

Louis

Not much we can do. From your logs, that NIC is definitely insufficient for the load being put on it.

Hi,
Thanks for having checked this issue. This machine is in a dev environment, i'll leave it like that - i've noticed another issue with the vmt (debian and ubuntu) can't see the NIC after U1 update (same with the last stable update)

No problem with intel NIC though

Please close the ticket.

Thanks.
