Guys I need Help,

Server Specs:

- HP Proliant G9 4cores CPU, Not Hyper Threading
- Windows Server 2008R2 Standard Vm, 4Cores CPU, 12Gb RAM

Ignition Gateway:

- ver. 7.9.6
- 45564 Tags
- 4 PLC connection
- MySQL DB
- 6 Client Stations

Issues in the Field:

- After a long Run of the Gateway CPU usage would go up to 100% which cause operational problems.
- When we Reboot the Gateway it will go back to normal.
- is there any fixed?

Using our Office Server Dell PowerEdge 24cores CPU & 128GB RAM, Support Hyper Threading:

- We Run the Gateway Server Vm with 8cores CPU & 12GB of RAM. it Works Fine
- But for our simulation Test.

~~Your system’s behavior sounds like the behavior of the old garbage collector on memory pressure.~~ Please show your ignition.conf file. (Use triple-backquotes above and below so it formats…)

Edit: Your performance page snapshot shows the G1 garbage collector, so that’s not it. But memory pressure could still be involved.
