I work with the original poster and wanted to make sure the problem here
is clear.  The 'out of file descriptors' message is coming from
Postgresql, not the kernel.  Thus, it doesn't make sense to me that the
max_files_per_process setting is too high.  I would think we need to
increase it so that Postgresql will stop generating these errors.
