## Symptoms

- * Traffic latency on VSX Gateway / VSX Cluster, which leads to outage after several hours.

* Without Jumbo Hotfixes installed, there is a memory leak, and traffic slows down until it stops after several hours of uptime.

* With R80.20 Jumbo Hotfix Take 103 installed, memory leak issue occurs even faster.

* With R80.20 Jumbo Hotfix Take 118 installed, CPU utilization increases.

* Kernel debug (fw ctl debug -m fw + drop) shows:

  * Repeated messages "*Instance 0 is currently fully utilized*"

    Example:

    `[fw4_0];fw_log_drop_ex: Packet proto=... dropped by fwkdrv_enqueue_packet_user_ex Reason: Instance 0 is currently fully utilized;`  
    `
    [fw4_0];fw_log_drop_ex: Packet proto=... dropped by cphwd_pslglue_handle_packet_cb_do Reason: F2P: Instance 0 is currently fully utilized;`
  * Traffic drops related to PSL streaming

    Example:

    `[fw4_0];fw_log_drop_ex: Packet proto=... dropped by fwmultik_process_f2p_cookie_inner Reason: PSL Drop: internal - streaming`
