The error "vmunix: file: table is full" or "File table overflow"
means that the maximum number of open files is exceeded.

This error condition can usually be corrected by increasing the
value of NFILE and/or MAXUSERS in the kernel configuration file
and rebuilding the kernel. Increasing the MAXUSERS parameter
will n turn increase the NFILE, NPROC, and NINODE parameters.

Youve exceed a kernel table called nfile.

To see what its currently set to;

sysdef | grep nfile

Then you need to increase it, build a new kernel and reboot. Best to use sam to do it.
We typically run our L classes around a minimum of 4000 and some big ones up to 16000

Hi,

You will have to increase the kernel parameters NFILE in order to be able to open more files.

Hi,

The error message you are receiving indicates that you have hit a maximum value in your system kernel. To fix this problem you will need to increase some values in your kernel and then reboot your system. The parameters in question most likely are:
'nfile' and possibly 'maxusers'and 'nfile' and 'nproc'

The best way would be to use 'sam'

sam --> kernel configuration --> Configurable Parameters
Select the parameters to be increased and increase them. You may find that one or more of these has a forumla. If you are unsure, you ask further questions. After increasing and saving you will be prompted to rebuild your kernel and reboot.

Also worth noting: parameters "maxfiles" and "maxfiles_lim" limit the number of files that can be opened per process. (root excluded, of course...)

maxfiles is the "soft" limit, and maxfiles_lim is the "hard" limit that cannot be exceeded.
