CA environment variables not being set?

[Shawn Smith <ssmith@ztec-inc.com>]

Hello everyone,
I'm pretty new to EPICS and I cannot find answers within the
documentation, so hopefully someone can help me understand the problem
I am having.

It appears that my CA is only using the default values from the
CONFIG_ENV file, no matter what I have set the system variables to.
The order of ops is as follows:
  setenv() to establish the env list EPICS_CA_ADDR_LIST,
AUTO_ADDR_LIST, ... MAX_ARRAY_BYTES
  iocsh(0x0)
  ( I have tried using epicsEnvSet() on all the variables here, but it
makes no difference )
  dbLoadDatabase()
  dbLoadTemplate()
  iocInit()

Any epicsEnvShow() calls after the iocInit() come back with the
correct values from either setenv() or epicsEnvSet().
I try to set EPICS_CA_MAX_ARRAY_BYTES to higher than the default 16384
to accommodate a NELM of 4000 points, size DOUBLE, but CA calls to the
pv come back with
"Read operation timed out: some PV data was not read. ... The
requested data transfer is greater than available memory or
EPICS_CA_MAX_ARRAY_BYTES"
I don't believe that I am out of memory because the ADDR_LIST
variables are not functioning properly either.

Is there any way to read back these values with Channel Access calls?
I am not sure where the problem might be, in the configure files or a
missing startup call?
This is version EPICS v3.14.9
Thanks for any help.
