Hi, @wdxxs2z,

Cloud Controller does set a limit on the number of file descriptors an app's start command can open, and the Diego backend applies that limit. I think as an operator it can be configured via the instance_file_descriptor_limit parameter in the CC config, but I don't think it can be configured on individual apps. If that's an important feature for you, I suggest that you discuss it with the CAPI team.

Thanks,
Eric, CF Runtime Diego PM

Thanks @ematpl
As an operator, this may Cloud_controller without open file_descriptor_limit configuration api, or may be the performance of the whole Cell into consideration, this parameter can't set separately for each application, I'll ask capi team.
Thank you.Close this question.
