Hi,
Usually you would have to increase the nfile parameter to solve this.
Take a look at the following thread : http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x42d5cf38d6bdd5118ff10090279cd0f9,00.html

Hope this helps,

As suggested by the error message, this is due to a kernel table (the open file table) becoming full - you can monitor this using:

sar -v 2 10

Look at the file-sz column - this tells you the current size of the file table, and how many rows are in use.

If you decide the table needs increasing in size, you'll have to re-gen your kernel - Go in the kernel section in SAM, and look at the 'nfile' kernel parameter.

Hi,

Run sar -v and look at the file-sz column. This will tell you the current-size and maximum-size of the system file table.

See man sar for more info.

Increase kernel parameter nfile to fix the problem.

HTH,

Dave.

Hi,

you need to increase the nfile kernel parameter.
This one is related to more parameters.
Use sam to increase the right one.

Hi Malki,

As all have already said earlier this is due to the nfile parameter.

One suggestion here:
You use 'sam' to increase the kernel parameter. The safest bet is to increase the kernel parameter 'maxusers'. This parameter, in turn, will increase all the relevant parameters automatically, 'nfile' being one of them.

for this change, I think that I need to reboot the server is't correct..?

I would suggest tuning only the nfile parameter as I am also a beliver in keeping formulas out of the system file. I'm not saying though that one is better than the other.

Yes, this will require a reboot.

I have another simlary problem
On other server, I have inode-sz parameter on max used when i use sar -v command
And I have some users whe can not logged to the server..
Is the limitation of ninode the source of this problem

Malki

You need to increase the value of ninode to a larger value. sar -v 2 10 will give you the cureent allaocation , these paramters are like the limits or boundaries in which the OS works , it si safe to increase it and monitor the same to achive a stable value . A good place to start would be to increase by 50% and again watch it . No on can login is these parameters get saturated.

A good palce is to look here :

Malki,
The inode table reported in sar -v is a inode cache. The size of this cache probebly has a upper limits but on my systems it is always almost full. Anyway, cache is only use for performance and it should not be a problem for login .
