I do have wordpress and q2a on same server, I know when user load is too much I can expect below kind of error but site is not coming back after this. I need to reboot server to fix this issue. whereas my wordpress site works normal after user load is low, it recovers back(wordpress is slow when I see below error for Q2A but never get any db error for wordpress). I feel this is real issue with Q2A but you may be having diff views. Could anyone explain me please. thanks.
some people already complained about this.
