Hi everyone!
Currently, we are monitoring a Cisco ASA which is running Software version 8.4(4).1. It is showing high cpu load (reaching 90%) at some hours, and our client (who is the owner) has asked us to troubleshoot this issue, since this is not a normal operating condition for the ASA.
We have checked over many forums and documents about "high cpu related to Dispatch Unit process", but we still don't know where to begin, and what steps we could recommend to our client. (We have only asked him to disable dns-guard, but it didn't help)
I have uploaded an archive, where I have extracted these outputs:
show processes cpu-usage sorted non-zero
show memory
show service-policy global
show interface
show run threat
And also I add this info from the running-config:
policy-map type inspect dns preset_dns_map
parameters
message-length maximum client auto
message-length maximum 512
no dns-guard
policy-map global_policy
class inspection_default
inspect ftp
inspect h323 h225
inspect h323 ras
inspect rsh
inspect rtsp
inspect esmtp
inspect sqlnet
inspect skinny
inspect sunrpc
inspect xdmcp
inspect sip
inspect netbios
inspect tftp
inspect ip-options
inspect dns preset_dns_map
I would appreciate any recommendations.
Thanks
Fabio.
