Hi,

View your /proc/sys/fs/file-max file to get the current "open files" limit for your system. If you want to set it (e.g. 65536) type:
"echo 65536 >/proc/sys/fs/file-max"

You can also check your High-Water-Mark in the /proc/sys/fs/file-nr file. There are 3 numbers, the first is your high-water-mark, the second are your actually open file and the third is the file-max-entry.

Best regards.

Frank

Hi,
this just happened to me. I increased the fs.file-max from the default 8192 to 10240.
I am running PostgreSQL on an Intel P4 with 3GB of RAM. How can I calculate what would be a good file-max without overallocating resources?
Regards,
Robert Mijango
