Insufficient memory for signal/pin

Insufficient memory for signal/pin was created by GStewart
While connecting my MPG to my latest retrofit, I encountered the "Insufficient memory for signal ...." message while loading EMC2
I rem'd out all my extra signals (I have not yet connected the toolchanger).
It switched to "Insufficient memory for pin ...."
So I removed some Classicladder assignments and I got it to come back up.
This machine has 64 Inputs and 32 Outputs connected to two Motenc boards, plus the 6 axis MPG from CNC4PC through the parallel port.
The computer has 2GB of memory.
I am a Linux newbie, is this a memory allocation problem or ???
Thanks

what version of EMC are you using? The HAL memory limit has been raised a couple of times along the way.

Sorry for the delay responding, I have been busy running machines.
I am using version 2.3.0 on this machine.
Thanks

in release 2.3.2 the HAL memory was increased. I would try upgrading to at least that release and try again.

Hello,
I currently working on a retrofitting a turret punching machine (Trump - Trumatic 180) with LinuxCNC, and I also met with this "Insufficient memory for pin..." error message.
If I delete some code from *.HAL file, the LinuxCNC starts without error message.
But I cant continue coding without more HAL memory...
Can anybody help me how to increase HAL memory size, and then how to rebuild LinuxCNC? (I am newbie in Linux... )
LinuxCNC version: 2.6 @ Debian.
H. Attila.

version 2.3 is so old , as we are now on v 2.6.9
perhaps updating will help , as a lot has changed in the meantime

try changing the value memlock in /etc/security/limits.d/limits.conf
i have not tried this myself , so it may not do as you wish , but worth a try

Hi,
I am facing the same issue with LinuxCNC 2.8.0
Before modifying the file in /etc/security/limits.d/limits.conf I would like to be sure about what it is suppose to do exactly. Which value should be modified? I tried to modify it and obtained always the same issue: insufficient memory for signal ... Has anyone managed to get rid of it, extending the memory doing some modification in this file?
Does this also mean that we are limited in the amount of signal/pin that we can create? Once the limit reached, which likely triggers this error, I would like to be able to extend it as I am already using a lot of signal an planning to use even more.
Thanks,
Nicolas

How many pins do you have? I am wondring if this is a genuine out-of-memory problem.
Which HAL component is being loaded when it goes wrong?
