Hi all,

I am getting this error on console

Could not open /usr/lib/dld.sl error no 000000023.

Please let me know what is this error and how to recover this file.

Last week this server went for live environment.

Is some kernal parameters has to be tuned ?

With Regards

Harpreet Singh

Hi Harpreet,

Definitely looks like you've hit a kernel limit. Have a look at running 'sar -v' to get the answer, which is most likely 'nproc' or 'nfile'. If this is the case, you will need to increase these values. ANother way to view these is through 'glance'. The best way to do this is through SAM, as you may some formulas set up for these parameters. If the problem occurred during the use of telnet you may need to increase 'npty', 'nstrpty' & nstrtel as well.

Basically the error means dld.sl (dynamic loader) can't load any more files into memory.
You should see similar error in /var/adm/syslog/syslog.log. Typically you wuld want to increase maxusers parameter and that in return will automatically bump up other parameters like nfile, nflocks, nproc and bufpages. Try doubling the value of maxusers.

Hi
Error 23 is file table overflow.
increase nfile.

Err 23 is indeed file table overflow & nfile needs to be increased but keep in mind that nfile is tied to maxusers - so it may be better to increase maxusers.
