what does file-sz refer to

[columb]

I'm running sar -v and getting the following

AIX b04001 1 5 0050DA1A4C00    01/17/05
 
13:22:39  proc-sz     inod-sz     file-sz     thrd-sz   
13:22:43  610/262144  977/510264  8668/8959   993/524288
13:22:47  610/262144  975/510264  8657/8959   1000/524288
13:22:51  611/262144  975/510264  8656/8959   1001/524288
13:22:55  610/262144  977/510264  8659/8959   1000/524288

I've been on the IBM web site to try and understand

1) what does file-sz mean
2) does it matter that it is so near the limit
3) what do I do about it

but I can't find any answers. Can anyone out there help please?

The first thing I did was man sar, then I searched the IBM web site. The sar man page (which is all that there is on the IBM site) has

Reports status of the process, kernel-thread, i-node, and file tables. The following values are displayed:

file-sz, inod-sz, proc-sz , thrd-sz
Reports the number of entries in use for each table.

So I have rtfm but I'm still in the dark. I don't know what a file table is. Please can you give me a little more.

Thanks

The file table for every open file keeps track of properties of the file:
- file status flag
- current file offset, or current file size in i-node table entry
- pointer to v-node table entry for the file
