File Descriptors - Linux / Unix Administration

Greetings, all. Can anyone tell me if there are any risks associated with increasing the number of file descriptors for an application/user process beyond the default 1024? I am running on Solaris 5.8....

    Default File Descriptors

    Greetings, all.

    Can anyone tell me if there are any risks associated with increasing
    the number of file descriptors for an application/user process beyond
    the default 1024?

    I am running on Solaris 5.8.

    Enjoy debugging some application that opens that many files at once!

    I suspect the risks are organizational more than technical except
    for programs using expect() system calls. More resources for a
    rootkit to use if you get cracked, more interaction of two programs
    opening the same file without checking optional locks, etc.

    Many of the original limits come from a time when memory was much
    more expensive.
