It seems that it is a known bug from a Debian package.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Ingolf Steinbach (ingolf-steinbach)]

This issue is still present in 1.8.4-2 (from 17.04). Currently upgrading to 17.10 is discouraged, so I'd rather not check whether it is fixed there.

However, please note, that https://github.com/tinyproxy/tinyproxy/issues/25 seems to have a fix for the bug.

[gesasgerol (ekkhsa-launchpad)]

I do have the issue on 17.10.

my temporary fix would be to change the logging to syslog in
/etc/tinyproxy/tinyproxy.conf
`Syslog On`

or to insert
`create 640 tinyproxy tinyproxy
`
into the /etc/logrotate.d/tinyproxy
```
# cat /etc/logrotate.d/tinyproxy
/var/log/tinyproxy/tinyproxy.log {
 rotate 14
 daily
 compress
 missingok
 create 640 tinyproxy tinyproxy
 postrotate
  invoke-rc.d --quiet tinyproxy reload > /dev/null
 endscript
 notifempty
}
```
Testet on Ubuntu 17.10

Please, note that it is possible to intall cosmic package onto bionic. Updating the version for bionic is stressless.
