Symantec™ Security Gateways Reference Guide - Sawmill

Log messagesCritical messages (600-699)267671 - Driver log messages at this level suppressedDescription: Due to increased volume, information log messages are no longer logged until conditions improve so thatlog services do not overload the CPU. This lets you allocate CPU cycles to continue providing user serviceswhile not logging the incoming connections.671 - Temporarily suppressing messages because the security gateway has reached log limits fordriver messages at this levelDescription: Due to increased volume, information log messages are no longer logged until conditions improve, so thatlog services do not overload the CPU. This lets you allocate CPU cycles to providing user services and not tologging the incoming connections.672 - Shutting down the security gateway because the intrusion detection and preventionloadable module is not respondingDescription: The security gateway is shut down but management connections are allowed. The IDS/IPS component maynot be responding because of improper loading, no buffer space, user daemon not running or some otherinternal error.For either gated or non-gated mode, the administrator can change the configuration settings so that analert level log message is generated and the security gateway is not shut down.679 - Kernel memory usage exceeding 75 percent of maximum memory limitDescription: The driver tracks memory allocation within itself. When memory allocation exceeds 75 percent of themaximum limit, this message is issued once. When the amount of memory allocated falls below 50 percentand then exceeds 75 percent, this message is issued again.The vpn stats global/Max_Memory command indicates the maximum memory allowed. The vpn statsglobal/Current_Memory command indicates the current amount of memory allocated by the driver. Thevpn stats memory command gives a subsystem the breakdown of memory allocation.The security gateway could either be under an attack or there could be a memory leak. You could increasethe maximum memory limit or a reboot may be required. Remedial action is highly recommended.
