Re: table overflow question

Thanks all,
I went reading about the nfile and it does look like it is the
problem.. I could rework the script to just dump to a flat file (which I
had in the past) and have another script read it in after the fact with
only one db connection.. but that's kind of inefficient..

He said he was using HPUX. On HPUX 10.20, the kernel parameters NFILE
and NINODE would be the things to bump up; I suspect 11 is the same.

The other direction to attack it from is to reduce PG's parameter
MAX_FILES_PER_PROCESS, but if you have to set that lower than 100
or so then you'd be better advised to fix the kernel.
