You are concerned about the memory load used by your proxy and it regularly informs you that its memory capacity is reaching the limit.
In many cases, this issue is due to the local Web filtering service.
In fact, by choosing to use this procedure, the proxy has downloaded the category databases and loaded 60 million websites into memory.
This initiative provides a fast, but memory-hungry categorization service.
To solve this problem you can either increase your system memory ( 8Gb) or prefer web filtering in ACls uses the same category system except that categories are hosted in the cloud.
