The current setting is 65535. Does it mean that this value is not enough? The current server only runs dfuseeos

[cppfuns]

Will this "open files" be continuously accumulatively occupied or consumed? I am currently modifying it to 655350. After observing for a period of time, the test transfer pressure during my test chain is constant. I don't know if this "open files" keeps occupying more and more, will there be a problem. If the default value of the system is not enough to support the operation of dfuseeos, should you give a default value check prompt, or open the order of magnitude at the lower limit of the given parameter?
