"Hi Guys! . Does anyone know the meaning of the mssage "Memory trolling not supported"??
The message is been recorded on /var/adm/messages file. It's a Tru64 UNIX V5.1A.
thanks ind advance."

The memory troller is a VM subsystem function that tests memory pages in the background. If the systems signals a problem while testing then it knows enough not to crash the box (it would crash on a memory fault during normal work). Apparently this is not always supported. My VM friend suggests to simply ignore this warning.

Of course if you have other real problems, but this message is the only indication you can find, that it still _could_ be valuable in drilling down to that real problem.

So the question becomes... do you think something is going wrong with the box or is is just the message that is strange? If soemthing else is goign on please try to articulate that to us for further help. If it is just the message: don't worry, be happy!

Have a great weekend you all,
Hein.

As I know, memory trolling is a feature only supported if cpu and memoryconfiguration (hardware side) honor it. It is a kind of "interleaving"...

[Dave Bechtold]

Hello,

Yes, this means that the sysconfig "vm" subsystem has vm_troll_percent attribute set to something other than '0' on a system hardware platform which does not support the Memory Troller. To disable the Memory Troller and turn off the warning use the following command.

# /sbin/sysconfig -r vm vm_troll_percent=0

Then review the systems /etc/sysconfigtab file and see if the attribute is set to a non-zero value and set it to zero '0'.

For more on Memory Troller see the Online Addition and Removal Guide in the V5.1B Doc set.
