Hello,
Our ASA 5525 (IOS 9.14.4.24) is experiencing high memory utilization.
This is what I see so far:
fw1# show memory
Free memory: 815972661 bytes (18%)
Used memory: 3575802776 bytes (82%)
------------- ------------------
Total memory: 4391775437 bytes (100%)
I checked the log level and found this:
internet-fw1# show logging setting
Syslog logging: enabled

Any idea how to lower the memory utilization?
I wasn't able to find any bugs related to my IOS version. Furthermore, this ASA model can not go above 9.14.4.24
Accepted Solutions
I located the article earlier. I eliminated the log level set to debugging on the buffer and cleared the counters.
I was not able to find any bug articles related to memory leaks with our version.
I am having some difficulties getting the Cisco CLI Analyzer to connect to the box. I disabled the local Win firewall at the source and enabled SSH for the source machine, however I get a window with a blinking cursor.
It seems like my jump box is closing the connection, not sure why though.
