Message in dmesg !

[Ivan Azuara]

Hi !

I was checking my server, and found a message using the command "dmesg", and show me the next:

file: table is full
file: table is full
file: table is full
file: table is full
file: table is full

Somebody know if i need to change some value in the kernel parameters ?

P.D. The server has HPUX 11.00/64..


Best Regards !

You need to increase nfile.

[S.K. Chan]

The max number of open files are exceeded. You can choose to increade "maxusers" parameter which would automatically increase "nfile". Use SAM for this.

Hi Ivan,

By default the nfile value is derived from the following formula

((16*(nproc+16+maxusers)/10)+32+2*(npty+nstrpty+nstrtel)

So you could also increase the nfile value by increasing the maxusers value. This has the added benefit of increasing other kernel parameters - such as nproc - as well.

But check your kernel the nfile may also be set as a static value & un that case changing maxusers would have no effect.

Rgds,
Jeff

After you do that you can still monitor using sar -v 2 5 to check the dynamic value of nfile and cron it for a day to know the saturation of these parameters and then tune them.
