Sudden error hoping to find the cause of it

  • Sudden error hoping to find the cause of it

    Hi there

    We recently got a serious error on the server and when I went through the logs the below error had pasted over 200 times in a short time period. I am wondering if anyone would know or recognise it so that I can narrow down where it came from or which plugin? ?( A reboot did stop the error but I would love to know the cause if possible.
