Our Cisco ASA5510 firewall has just started to receive these "memory allocation errors". The first time this happened, it occurred after the firewall had been up for 294days without issue. To fix this the first time, I reloaded ASA. It's happened again this morning but, I've taken a 'sho tech' before it reloaded.
We did enable the WebVPN part more than a year ago. It's not being used but, still enabled. The memory usage averages approx 184MB.
As the memory allocation error has happened twice now, if it happens a third time I'm going to disable the WebVPN part. As this link refers to newer code that fixes an issue with memory allocation errors related to WebVPN.
Should I disable the WebVPN or upgrade the code?
I'd prefer to stick with the code and just disable the WebVPN.
What are your thoughts?
