If your IOC is busy the caget default search timeout of 1 second may be
too short, have you tried using 'caget -w 5 tcs:ak:astCtx' say?

I have never seen an EPICS_CA_ADDR_LIST as long as yours, but given that
you seem to be searching multiple subnets maybe you do need that.
I don't think setting EPICS_CA_AUTO_ADDR_LIST to YES will make any
difference to this behaviour (your epicsPrtEnvParams showed it as YES
already, so unless you have explicitly changed it for the client you're
probably already searching your local subnet as well).
