I think I have found the problem. I did the following:
* Replaced the latest version of web2py with an older copy (1.95.x) which I
have been using with apache.
This helped me to get admin's access to the errors back. And then I
could repeat the process one of the users used when she experienced problem
and that ended in a memory error.
* Changing uwsgi to run 1 x 160Mb process in stead of 2x80Mb processes
solved this problem.
