We are testing new release 8.0 with PIX 515E ( 64 MB RAM / 16 MB Flash ). It seems that it's working fine when the firewall boots, but allocated memory is always over 53 MB, also "211001 Memory Allocation Error" message is continously received. After some hours the firewall begins to block incoming connections and "211001 Memory Allocation Error" message floods the log.
We have disabled some protocol inspection ( ESMTP, H323 ) and it seems that it works better.
It's possible to upgrade 515E ( Restricted ) to 128 MB, ot is it only possible for Unrestricted license ??
