CS-Studio (like most Java applications) has it own preferences for these rather then using the env vars. Preferences -> CSS Core -> EPICS for auto_addr_list and addr_list.

Those results are consistent with too-small of max_array_bytes. The client connects to the server, but cannot receive the data for the large array. 

Note, you need to restart CS-Studio after changing the EPICS network preference settings or max_array_bytes for the change to take effect.
