We are seeing extremely high DNS response times on the MWG 126.96.36.199.0 and this is impacting users onsite. We are not seeing the same response time in nslookups on the CLI of the proxy, but any client connecting through the mwg is getting massive timeouts.
The only indicator that we are having a problem is the Average Processing Time in ms for DNS Lookup under the Performance graphs in the GUI vault immediately to the 20k and above. We are unable to see this activity in any log file in the system and cannot seem to find out why this is happening. The resolution for this is to do a service mwg restart, which brings response times back under 100ms.
We need to know what could be causing this in the mwg processes and how to resolve it. As a workaround, we are trying to figure out how to read that number and restart the service automatically after a set amount of failures. This is not going well.
Any help or insight would be greatly appreciated.
We cannot update the software on this box at this time due to EOL status.
Any help with this issue would be greatly appreciated.
EOL is not related for the update process. To get the appliance updated you only need an active and valid license to start this process. Current main release is 188.8.131.52 for today.
