Thanks in advance.
I am unable to upgrade IPS 4240 to the latest signature version showing error
"Cannot parse the current config of the component "signatureDefination" and instance "sig 0"
Please suggest if any issue...
as per the show tech i troubleshoot and analysed in various forum found parse error could occur only when signature update modify some signature which they wouldnot allow to change....hence it generates an error................
Similarly it shows the error "error sending sensorApp control transaction " during upgrade.................
Any evidence about IpDualNode non-zero error ???
Thanks in advance....
You are likely hitting a new bug CSCtz29196. It was just written up today, and may not be available on the external Cisco.com page yet.
The bug is "Unable to upgrade signature package to S639 or S640 when 3255/0 is tuned".
Signature 3255/0 was modified in S639 in a way which may not be compatible with previous edits made to this signature.
This will be corrected in the next Signature Update.
I have not looked at your show tech output, but there may still be other issues on your sensor that Sawan is referring to.
Sawan is likely looking at errors in the main.log portion of your show tech output.
