Cannot load vrmesh file @ 1001th vrmesh

Uf, these issues are never easy to resolve.
It is good that we know where the problem is and hopefully it is something easy to fix.

We'll be happy if you let us know what the final solution is.

Again, thanks so much for the help narrowing down this one.

Earlier, when we ran CentOS 6 and used init.d scripts to start the Tractor client service, defining limits for the service was not needed as it seems the system environment was inherited. But now when we are using CentOS 7 with systemd, it seems you need to configure these things explicitly for systemd services.

So, since I use a systemd script to manage the Tractor client, this is what it now looks like:

/etc/systemd/system/tractor-blade.service

[Unit]
Description=Tractor Blade Service
Wants=network.target network-online.target autofs.service
After=network.target network-online.target autofs.service

[Service]
Type=simple
User=iruser
ExecStart=/opt/pixar/Tractor-2.2/bin/tractor-blade --no-sigint --debug --log /192.168.0.226/pipeline/logs/tractor/%H.log --engine=192.168.0.224 --supersede --pidfile=/var/run/tractor-blade.pid
LimitNOFILE=500000
LimitNPROC=500000
PIDFile=/var/run/tractor-blade.pid

[Install]
WantedBy=multi-user.target

I also have the limits set system-wide:

/etc/security/limits.conf

*         hard    nofile      500000
*         soft    nofile      500000
*         hard    nproc       500000
*         soft    nproc       500000

With these settings, we can now successfully render the Maya scene with V-Ray which needed to load a humongous amount of vrmeshes CentOS 7/Tractor!

Ok then, glad that it works now. Also very useful information for us to know.

Best regards,
