PortScan Shun Low memory error :-(

Hi

I had to switch off port scan shunning for possible offenders becaus I got this error

LU allocate connection failed

Although there is only 191Mb used from 256Mb

It is a ASA 5510 Sec Plus.

Is there anything else I can try ? I mean the CPU was only @ 2% when busy !

IOS V8.0.1 is running.

I would be grateful for any ideas..

Also is it possible to update the DRAM on a 5510 ?

Thanks

Re: PortScan Shun Low memory error :-(

The Memory Scan feature adds a low-priority background process that searches all installed dynamic random-access memory (DRAM) for possible parity errors. If errors are found in memory areas that are not in use, this feature attempts to scrub (remove) the errors. The time to complete one memory scan and scrub cycle can range from 10 minutes to several hours, depending on the amount of installed memory. The impact of the Memory Scan feature on the central processing unit (CPU) is minimal. To view the status of the memory scan feature on your router, use the show memory scan command in EXEC mode.
