Hello guys,
one of my customer reported 802 error in his server. Could you help me how to track circumstances leading to this error?

Thank you

Hi,
Check the memory status of the server.

Hello,
could you elaborate? The instance is hosted on VMware hypervisor. I talked to the guy on the phone and asked him some basics but all I was able to get from him was:
Max Server Memory option is set
There is only one instance on that VM
It happens during nightly ETL loads - about once per month or two

I will know more as I see the instance. I'm just asking where would you suggest me to look first.

First I thought about setting alert for 802 error to execute job which would dump information about running jobs and some DMVs.

What do you think?

Error 802 is "Insufficient memory in the buffer pool", which suggests there's insufficient memory.

Probably too much done in that job and not enough memory allocated (or incorrect VM settings)

Thank you all very much for your feedback. I have deployed Management Data Warehouse to the instance plus added custom collector for following counters to get more information about the instance:
Lazy writes/sec
Checkpoint/sec
Free List stalls/sec
Free Pages/sec

Page Writes/sec
Page Reads/sec
