Hi List,<br>
<br>
Im not sure if this is a bug with MapProxy, but i experience the
following problem a few times:<br>
<br>
I am running a seed on a debian system. While the seed is running,
the default logrotate of debian reloads the apache to change the
logfiles.<br>
And here comes the problem: If a seed is running and apache is
reloaded, i get the following error in MapProxy:<br>

MapProxy (1.2.1) stops and does not continue the seed. <br>
I tried this manually and could replicate the problem. Doing a
"apache reload" stops the seeding process, while a "apache restart"
is no problem (MapProxy continues its work).<br>
The quickfix i have done is to edit the /etc/logrotate.d/apache2<br>
and change the line with "reload" to "restart".<br>
<br>
If this is a bug in MapProxy, maybe it can be fixed in upcoming
MapProxy versions?<br>
<br>
