We have 2 ASA 5520's running Active/Standby with the cable based failover. At random times perhaps once our twice a week we will get calls that RA VPN users cannot connect, RA users connect with the Cisco VPN client. Also most often during this time we cannot telnet into the "primary" ASA, but we can "usually" access it via the ASDM where we will see that the memory utilization is in the upper 90% range and perhaps as high as 98% consistently. To help temporarily solve the issue we have to telnet to the "secondary" ASA which we can usually access via telnet and perform a "failover active" which will failover the primary and make the secondary become the active and vice versus. Has anyone seen this issue. I have opened up several TAC cases and have not had much help. Thanks in advance!
I have this problem too.
