cacti does not draw after memory increases

[Abeke]

The cacti server stopped due to insufficient memory. Then they made an expansion of the server where cacti is located. And after that I stopped drawing graphics These are the last errors:

It is unlikely to be memory increases, more that software/permissions have been updated. Looking at those logs, it looks like you're running a quite old version of Cacti.
