As per our analysis , we can see that only the front end trace has been captured, however, we also need to look in to the backend communication as well.
For that we would need NetScaler trace without filters. If you think that the trace file will be too huge, kindly filter the trace with the DNS servers’ IPs as well. If we don’t have the communication to the DNS servers captured, the analysis will be incomplete.
Once the traces are provided, we will be looking in to the traces tomorrow morning.
Also, the build 11.0 68.10 is not a very stable build to be on, hence, we would recommended you to upgrade to 11.0 68.12 which has been in place for 11.0 68.10.
