Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Hi Chris Huys,

1) I am not able to understand "61/4 = 15.25", please explain this?


2)Why do you want to run "who -u"?

3)what is the difference between "ps -ef" and "ps -el"?

Hi Senthil:

> 1) I am not able to understand "61/4 = 15.25", please explain this?

Look at your 'vmstat' data and *read* the manpages for the meaning of the values!

> 2)Why do you want to run "who -u"?

What happens if a client session (as from a terminal emulator) aborts? Do you have old sessions, perhaps consuming resources running?

> 3)what is the difference between "ps -ef" and "ps -el"?

Again, run the commands; look at the different output; *read* the manpages and see what you might learn.

Regards!

Hi,

> 61/4 = 15.25
"vmstat 5 5" output showed 61 blocked processes.
4 is the number of processors in the system.

61/4, equals, to the part in the load average that, is the result of the blocked processes.

I.e. if you wouldnt have had any blocked processes, the load average would have been
load average: 15.28 (-15.25= 0.03), 15.27 (-15.25 = 0.02), 15.27 (-15.25 = 0.02)
i.e.
load average: 0.03, 0.02, 0.02

who -u
Im pretty sure the blocked processes are shell processes, that couldnt exit "normally", thats why, who -u would show them.

ps -el / ps -elf, gives the wait reason in hex, not that interesting, but just a hunch from me.. anyway blocked processes should there be allready for a long long time, doing nothing .. and as you mentioned that the amount of processes constantly increases, this is probably because of the number of blocked processes increasing, checking for a few days which processes are causing the process list to increase, should also lead you to the blocked processes..

killing, kill -9, these blocked processes, once you find them, would then 'workaround' the problem..

> more sleeping process (217)

A sleeping process is doing nothing so they do not contribute to the load -- unless these processes wake every few milliseconds, run a few instructions and then go to sleep again. That may be exactly what is happening. What are the 217 processes? Are they shells? If so, these may be orphaned logins caused by users that do not logout properly and the SIGHUP normally enabled in /etc/profile has been turned off.

Because of the long time (200+ days), it is highly likely that these processes weren't terminated when the user disconnected and they are spinning around trying figure out what to do. The load factor is a measure of the number of processes waiting to run or actually running. These orphaned processes are probably running for a short time several times a second. That's why there is almost no user time recorded.

I have also seen this as a largepages issue with 10.20 coupled with a fairly messed up patch problem with disk mirroring. The symptom is that the largepages table is constantly filled. The fix is to disable large pages in the kernel (after a reboot).

(Better to use: ps -fp 17305
Unless you want the children too.)

>1)How to solve the issue?

You don't. Reboot or ignore them.
Probably a NFS hang?

>2)How to enable SIGHUP in /etc/profile?

What do you really want to do?
If you want to ignore it, you run each command or script with nohup(1).
If you want to block it, you can use the trap command. But this should be in individual scripts and not in /etc/profile!

(Ah, what Bill said.)

If kill -9 doesn't work, it isn't likely SIGHUP is being disabled is your problem.
But you can check to see if "1" is on the trap commands in /etc/profile.

Hi,

DH> You don't. Reboot or ignore them.
Actually the system will eventually have filled up the whole process list, controlled by nproc kernel parameter, and will not be able to create new processes after that, which will then end up in the system needed to be rebooted.

For the rest install the latest posix?-sh patch, reboot the system and if that still doesnt solve the problem, then check how the orphaned shells are created, probably some user(s) doing something specific f.e. exiting the app in a specific way, as I suppose that not all users all the time are creating this orphaned shells, and work from there.

If all these shells can't be killed with kill -9, there isn't much that can be done.
If they are hung over NFS, then that needs to be more reliable.
