I have tried to send an email via Mail>>operations>>send email and it crashed the server. I did not happen once again (yet).
We use an external gw for emails, though external gw does not start on the linux server (it starts on the windows). Error on linux is 2017-03-09 13:54:25 database cache may be max 80% of physical RAM (physical RAM is: 0bytes, attempted to use: 100000bytes for DB cache)
What could be the reason? Here is an excerpt from the log:
