Hello Team,

In a customer cluster facing the issue with too many open file descriptors. The CDP version is 7.1.5

Bad : Open file descriptors: 31,364. File descriptor limit: 32,768. Percentage in use: 95.72%. Critical threshold: 70.00%.

Can you please share how to mitigate this issue? Is it okay to increase the Maximum Process file descriptors and what would be the recommended value?

Best Regards
