I'm having the same troubles after upgrading to python3 using Apache
with libapache2-mod-wsgi-py3 4.5.17-1 on Ubuntu.
I did delete all session files, and I am using fresh source code of web2py
(R-2.17.2).
I'm running several applications in web2py, and when i restart Apache they
work for a while. Then at some point later, and I haven't figured out what
initiates the problem, I am getting:
Traceback (most recent call last):
File "/home/ubuntu/mnt/web2py/gluon/main.py", line 445, in wsgibase

File "/home/ubuntu/mnt/web2py/gluon/main.py", line 207, in
serve_controller
raise HTTP(response.status, page, **response.headers)
gluon.http.HTTP: 200 OK
During handling of the above exception, another exception occurred:

if len(pool) < self.pool_size:
TypeError: '<' not supported between instances of 'int' and 'str'
In my apache error log I see this:
