Several companies in Petrochemicals, refinery, utilities, Oil & Gas, Pharma still have OpenVMS in operation. The last one I encountered was in 2012, I was told it had been running for 10+ years nonstop. I mostly worked with OpenVMS on VAX in mid-90s. They were the workhorse of manufacturing/process control systems.
