High load average & a root d3 process

What is the d3 or d3 _slave process? I haven't noticed this before but today it's showing up as my top process under the user root & my load averages are unusually high for the number of users I have on the system.

Thanks in Advance!

Re: High load average & a root d3 process

Sorry for leaving that out! Running HPUX 11.31 on a rp4440 pa-risc. The ppid is showing 1232 for all of them. Could this be from a remote login that was dropped?

It looks like whatever it is, it just keeps running today over & over. Is it safe to kill them all?

Re: High load average & a root d3 process

This looks like a runaway login attempt where the name of the login shell is d3 (that's why there is a dash -d3 in the listing. Look at the password file:

grep d3 /etc/passwd

It is probably a mistake made by a user trying to create a new shell or menu script and they used the chsh command to change the shell to d3.

Re: High load average & a root d3 process

ps -ef|grep 3762, for an example, you need be sure th eprocess can be killed. this one is very old, find out what it is...maybe a reboot will clear them all.

Re: High load average & a root d3 process

System is a trusted one, so looking at passwd gives me nothing. I found one user who has root access that may have accidentally done something, so killed their process but this D3 thing still remains. I guess I'll be doing a reboot on Sunday when I have to install patches anyhow.

Re: High load average & a root d3 process

No need to grep anything for ps PID numbers:

ps -fp 1232

You need to track down the parent process (1232). It may have disappeared but I also see registrar with a PPID of 1232. That is part of the EMS/diagnostics reporting system. A reboot will certainly fix this problem.

Whether the system is Trusted, shadow or standard security, you can always read (grep) the passwd file:

grep d3 /etc/passwd

Now if nothing is showing then there is no user shell by that name and the mystery grows deeper. Possibly an option (-d3) was stored as a filename and the parent is trying to automatically start this file. However, the process d3_slave may indicate that this process is associated with something else. Look in the usual places:

find / /usr /opt -xdev -type f | grep d3

The parent directory should give some clue.

Oops, I just spotted the first line. PID 1232 is inetd and it has been creating the -d3 processes. Look at /etc/inetd.conf to see if there is a line continuation problem where -d3 is not part of a daemon command line -- but should be.

Re: High load average & a root d3 process

Thanks Bill!

Here is a line from the inetd.conf file that may be the culprit:

udssltelnet stream tcp nowait root /usr/ud/bin/udtelnetd -d3

(However it does appear on a single line in the file.) This server hosts a unidata database and I believe the d3 is setting the log level to high; so I'm going to change it to 0,then restart inetd & see if that does it. IF not then I suspect that its something to do with hp services because this is part of what I see when I do the find / /usr/opt -xdev -type f | grep d3:

/opt/hpservices/mqueue/ST00d3_STAT_HP_Services.mot
along with additional lines of ST01d3 through ST07d3.
