Hi,

If the count in ca_create_subscription is > 1 and the type is
DBR_TIME_STRING, is the event_handler_args.dbr->value set to an array of
strings?

Also, when I try to do a ca_create_subscription on the excas pv named
albert (1000 elements), I get from the SEVCHK:

CA.Client.Exception...............................................
    Warning: "The requested data transfer is greater than available memory
or EPICS_CA_MAX_ARRAY_BYTES"
    Context: "ca_create_subscription"
    Source File: ../ca_monitor.cpp line 163
    Current Time: Fri Jan 28 2011 13:23:19.178091145
..................................................................

However, if I run the included camonitor tool on albert, it works fine.
Would this be because I am requesting the subscription with the
DBR_TIME_STRING?

Thank you again for your time,
Patrick
