Fixes
The following fixes are included in this hotfix:
-
Fixes an issue related to receive buffer exhaustion that could impact the ability of the gateway to process traffic. For the gateway to accommodate resetting connections (TCP RST), information from the last packet received must be retained (receive buffer). If the active session volume is high, there is a risk that the receive buffer can become exhausted, causing the gateway to not receive new packets. This scenario can occur more commonly from half-opened connections related to SYN floods (intentional or unintentional). This fix extracts the necessary information from the last packet of each active session and stores this information in a buffer that is large enough to accommodate the gateway active session limits, eliminating the possibility of buffer exhaustion.
