718.0. "Controller Process permanently in LEF-state" by HLSM04::GERRIT (Gerrit Woertman, UTO, 838-2535) Wed May 10 1995 14:40

With PCM V1.5-006 running on Alpha/OpenVMS V6.1 we had the problem 
that one of the systems produced that much output that the controller
process wasn't able to handle it, and went finally in a LEF-state, waiting
for some I/O-completion.
The result of this is that all the 16 systems handled by this controller
process are unreachable, and no console-output is logged.

We placed a call at MCS SSO-UTO, call 93800; the call was handled
by Ton UTRTSC::Dorland.
Ton advised to upgrade to PCM V1.6

Last monday I have upgraded to PCM T1.6-001 (dated 5-may-1995).

Well, we still have got the reproducable LEF-problem...

Besides a new problem arises: to get the OPCOM-messages of my PCM-station
I had already under PCM V1.5 a pseudoterminal (without problems); now
running PCM T1.6 also the controller process governing the pseudoterminal
comes in a LEF-state...; this is also reproducable.
To get some systems alive, I have disabled my pseudoterminal for the moment.

Now again I had my original LEF-problem, and I have made a crashdump
of my system. Ton Dorland will have a look at it.

	This is interesting considering that the IPC code is totally different between 1.5 and 1.6. It will be interesting to see what Ton finds in the dump. Regs, Dan
718.2	Stuck in SYS$WAITFR...	UTRTSC::DORLAND	There's always one more bug!	`Fri May 12 1995 11:22`	13
	Well, the dump (and the life system which has the same problem) do not tell very much. The controller process has enough resources so there is no resource problem. I see that it has several I/O's on LTA ports, and the program is now just waiting in SYS$WAITFR after doing a SYS$QIOW. In other words, it is expecting a response from one or more LTA ports. It looks that it is doing this in a synchronuous manner (without a time-out) so it got stuck there. Without the source code it is difficult to tell what is really going on here. I'll put the dump on UTRTSC::DUMPS:[DORLAND] in case you want to have a look at it. Ton
718.3		PBUNIX::pgb	And through the square window...	`Fri May 12 1995 12:54`	18
	Ton, Are you sure thats where it is stuck?? The reason I ask is that the only place we do a SYS$WAITFR is in a piece of code that is latent and never used by the daemons!!! All our QIO's to the LTA ports are asynchronous, the AST routine which is fired after data arrives causes a work packet to be placed on an internal queue. I am afraid that I am not very good looking a system dumps, maybe Dan if you are reading this, you could take a look as you have access to the sources? Cheers, Phil
718.4	LEF situation "not improved" in T1.6	HLSM04::GERRIT	Gerrit Woertman, UTO, 838-2535	`Fri May 12 1995 14:27`	182
	Hi, as I stated in note 725.4, my situation became worse after upgrading to T1.6 Ton Dorland is right, it is working sequential. In this note .0 I mentioned that my pseudo-device on the PCM-station was causing a hang of a controllerprocess, within a couple of seconds (it runs on an AXP) after starting PCM, and that is a behaviour I didn't have in V1.5! Below you can find: $show sys, and $ cons stat/all, where the PCM-station HLCC00 is number 17, and the rest of the systems 18, 19 are not even connected.
