Hi Niranjan,
The default max number of subsystems is set to 1024, please use nvmf_set_max_subsystems RPC to modify it.
Could you double check if you've encountered the issue after 1024 or 1025 controllers ? If there is an off-by one error somewhere here, please report it to https://github.com/spdk/spdk/issues.
Thanks,
Tomek

Hi Niranjan and Tomek,
We use one of the max allowed subsystems for the discovery subsystem. I think this explains why Niranjan can only create 1023 subsystems instead of 1024.
See nvmf_add_discovery_subsystem() in module/event/subsystems/nvmf/nvmf_tgt.c.
Regards,
-Jim

Thanks Tomek ! I started my spdk controller count from 0, so it should
ideally go to 1023 to make it 1024. If i start spdk controller count from
1, it goes to 1023 but ideally it should reach 1024.
