Anti-Bot is dropping traffic although it is disabled
The mal_conns table has reached its limit.
In R80.10, the timeout of each entry for mal_conns table changed to 130 seconds [instead of 10 seconds in R77.30]. When working with R80.10 VSX, the mal_conns table limit will be 25,000.
When the mal_conns table reaches it's limit, it will drop every connection that should be inspected by Threat Prevention blades.
