ACE module connection drops

Unanswered Question
Mar 10th, 2009

I am facing an issue with Cisco ACE module. Have 5 servers serving the connections for applications. However, during peak hours there is lot of dropped connections.

Also have lot of fragment reassemble.

Please help how to go ahead troubleshooting the issue.

I have this problem too.

I'm having a similar issue. I was told by cisco that the max connection rate is 120k and max concurrent conns is 1 mill

Thanks Man.

Is this documented any where on the Cisco Site.

Or can be known only by the TAC engineers.

it is on the cisco site. In the ACE datasheet to be exact. But I'm talking about the appliance. Not sure about the module. But should be the same. Only thing I was not sure was whether the same limits apply to the base license package, or are the figures lower for the base license. Cisco says that the numbers are the same for the base package.

however I'm yet to verify it on the field

Packet drops and connection drops can also be related to ACE module througput capacity.  Do see the output for "show resource usage all" to see if values for "Denied" is getting increased gradually for any resource parameters. It can be connection rate, bandwidth, throughput etc.

Do you see the denie counter increasing with a show resource usage all?

Do you see the failure counter increasing with a show serverfarm {name} detail?
