Hi,
Categorization failed occurs frequently in Endpoint Web Protection.
I find many messages of category="0" in eplog.
When this message outputs, I can access the blocked category.
If "Categorization failed" is blocked, Web access will become extremely slow.
And the access permitted category is also frequently blocked by Categorization failed.
The performance or the locations of sxl servers are insufficient?
Web access is comfortable when permitting Categorization failed.(The message of category="0" is many output.) Therefore, I think that the line which I'm using is not the cause.
