vmunix: file: table is full

[DESMOND KOH]

Hi,

I am receiving "crt0: ERROR couldn't open /usr/lib/dld.sl errno: 000000023" message when I tried to perform any command on a HPUX 11.00 machine.
According to the replies in this forum, it's due to the file table is full and need to increase the "nfile" parameter in kernel.

I also checked the "file-sz" value using sar -v command and found it's true that the number is reaching the limit.

Just wondering before I re-tune the nfile parameter, is there a way for me to find out which processes is causing the number of file open increase so much?

Your help is much appreciated. Thanks!

Your best bet with this type of problem is installing 'lsof' and finding which files could be affected.

You can get 'lsof' here:
http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.61/

Here are some examples on it's usage.
# lsof -p

To see all the open files associated with a particular command.

# lsof -c midaemon

User name.

# lsof -u
# lsof -u

processes being used via a socket.

# lsof -i tcp:23
# lsof -i udp:123



Is something that has just occurred? WHat is the current setting?

Hi Michael,

This problem has just occurred recently (2-3 days) ago. When I perform the sar command, I got the following result:

# sar -v 2 5

HP-UX S34KLJ74 B.11.00 U 9000/800 04/16/03

15:15:58 text-sz ov proc-sz ov inod-sz ov file-sz ov
15:16:00 N/A N/A 436/1600 0 2189/8318 0 5299/6583 0
15:16:02 N/A N/A 437/1600 0 2185/8318 0 5305/6583 0
15:16:04 N/A N/A 437/1600 0 2184/8318 0 5305/6583 0
15:16:06 N/A N/A 437/1600 0 2184/8318 0 5305/6583 0
15:16:08 N/A N/A 438/1600 0 2184/8318 0 5315/6583 0

The current setting is:
(35*(NPROC+16+MAXUSERS)/10+32+2*(NPTY+NSTRPTY+NSTRTEL))
which is equals to around 6500.

I also downloaded the lsof binary and executed the lsof -u command with different user id (pls find the attached output files). How do I determine the 5000+ openned files belongs to which process/user?

Try the one liner that i'd pasted. using lsof, it gives count of files opened by each process. you may sort it in descending order using sort command with -n option.

- ramd.

sorry - read that as posted instead of pasted, what a vast change it makes to the meaning. ;-)

Also this -
sort -n is used for numeric sorting. for sorting in descending order you would use -r option and so the command would be -

$ | tr -s " " | sort -t" " -n -r -k 2,2

- ramd.
