I have often seen that a copper shape for some reason causes this.
One way to find out is to one by one removed a copper shape and then pour the planes until you don't get the fatal database error.
Then you have found the copper shape(s) that may be causing the issue.
The solution is prabably just to draw the shape again.
I've experienced system memory in the past.
Pour few layers at a time.
As Klaus mentioned above, if any copper shape causing it you will be able to narrow down the cause.
What version of PADS are you using? We did a lot of improvements to copper pour in PADS VX.2.1.
Thanks for the suggestion, the solution you suggested is helpful to solve the Issue.
additionally I have removed couple of plane layers with GND plane pouring in it and Used common layer for GND plane.
Now I can able to check connectivity.
Thanks for Timely response, I just try Klaus suggestion and additionally removed couple of common GND plane layers.
Its working, I can able to run connectivity now.
Am using PADS LAYOUT 9.4.
