Since I upgraded my Vigor2862 to 3.9.6_BT I've started to see lots of two syslog messages

[Pass][Unknown DNS query type][Hostname= followed by url across many sites internal and external to my LAN
[CSM_AE][Insufficient Memory](4)

Anyone else have these and any suggestions on cause please?

Draytek have had issues with a previous firmware (Now removed) and some seem to be having issues with this one too re syslog so....

I use syslog and the data flow monitor too and updated in this way....

I updated my firmware to 3.8.6_BT 7 days ago and mine's stable but........

I disabled syslog and the data flow monitor first, rebooted then i used the RST firmware to update.

After rebooting i reconfigured the router and then at the end i re-enabled syslog and the data flow monitor.

Been stable since update.

Two very noticeable differences, before update the router was consistently using i think it was 3% of the CPU and 86% of the available memory.

After update the router is now using 13% of the CPU and only 56% of the available memory, a significant difference for whatever reason!!
