[APPFW]”File too large” raises when upgrading appfw default signature “*Default Signatures”

To upgrade the signature manually by command lines in command mode, steps are:

1. Login to ADC server

2. Ensure to enable appfw feature.

3. Ensure auto-update URL is configured and auto-update is enabled.

4. Ensure that the ADC has connectivity to auto-update URL

5. If any proxy present, please configure the proxy ip and port. If no proxy is present, go to next step.

6. Go to URL shell and execute the following command:

/netscaler/auto_update_signatures

Size of V90 signatures has been decreased to < 2MB, which will kill the issue, in other words, there will be no this issue in future upgrade(or auto upgrade) to V90 onwards.
