    Ingres reported the following warning on startup:

    WARNING!!! The recommended file descriptor soft limit for the NET Server to service 64 inbound, and 64 outbound connections is 261. The current file descriptor soft limit is set to 256.

    syscheck:
    Checking host "myhost" for system resources required to run
    Ingres...

    614 file descriptors per-process required.
    256 is the current system soft limit.

    Your system has sufficient resources to run
    Ingres.

    ulimit -a
    time(seconds) unlimited
    file(blocks) unlimited
    data(kbytes) unlimited
    stack(kbytes) 8192
    coredump(blocks) unlimited
    nofiles(descriptors) 256
    vmemory(kbytes) unlimited

    ulimit -aH
    time(seconds) unlimited
    file(blocks) unlimited
    data(kbytes) unlimited
    stack(kbytes) unlimited
    coredump(blocks) unlimited
    nofiles(descriptors) 65536
    vmemory(kbytes) unlimited

    Don't know why there is such a big difference between the soft and hard limits?

    Trying to understand what might have changed to cause this warning.

    Thanks
