I have all of the servers disabled on this IOC:

However the PVs are still being served:

 

dbracey@xyzzy:~$ pvxget ABC:XYZ_CTRL_SYS:AMP

ABC:XYZ_CTRL_SYS:AMP

    value double = 10

    alarm.severity int32_t = 0

 

epics> epicsPrtEnvParams

EPICS_IOC_IGNORE_SERVERS: rsrv qsrv2

 

I am just guessing at how things work, so I must have made a wrong assumption. 

Can someone explain what’s going on?

What does `pvinfo ...` show?

Maybe another instance of the IOC running...
