[Orca-users] Re: How can I regenerate my graphs when orca wasn't running for a while?

[Waltner, Steve]

In addition to changing the nfile kernel parameter using SAM, did you also
use the limit/ulimit command to modify the user limit for the number of open
files. You need to increase both values to be able to open more files in a
single process.
