NFS Server not responding

[MarcelW90]

Hello there,

i have the following scenario which causes me some problems during NFS write jobs.
I have a shared dataset via NFS for 192.168.10.0/24
The mount on two servers works without any problems.

But in case both servers want wo write to the NFS share, one of them gets a timeout to the FreeNAS Server:

Code:

Nov  4 00:43:59 pve-n2 kernel: [ 1992.272556] nfs: server 192.168.0.10 not responding, still trying
Nov  4 00:43:59 pve-n2 kernel: [ 1992.278317] nfs: server 192.168.0.10 not responding, still trying
Nov  4 00:43:59 pve-n2 kernel: [ 1992.291123] nfs: server 192.168.0.10 not responding, still trying
Nov  4 00:43:59 pve-n2 kernel: [ 1992.303939] nfs: server 192.168.0.10 not responding, still trying

I checked the logs on /var/log/messages but cant find anything regarding this problem.

I use FreeNAS-11.2-U6
RAM: 8GB
CPU: Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz
HDD: 6x 2TB with ZFS-RAIDZ2
ifconfig:
