## Symptoms

- * Connections stop passing intermittently through a Cluster in Load Sharing mode.

* Connections pass as expected through the same Cluster when it is configured in the High Availability mode.

* Kernel debug on the Cluster Members "`fw ctl zdebug + drop`" shows that the cluster drops the connections with:

  "`fwmultik_process_f2p_cookie_inner Reason: PSL Drop: No connection`".
