no stderr / stdout in the log files

[krychu]

Hi,
I'm using chaussette with circus and meinheld. But I cannot get any stderr / stdout messages from the webapp even though these streams are redirected to the log files. I know that the webapp throws some exceptions but the log files are completely empty. If I run webapp manually without using chaussette I do get all messages in the console. Can it be that chaussette swallows the messages? Or perhaps meinheld? Or perhaps I'm missing something in the configuration? Or perhaps stderr / stdout are not correctly captured because of the virtualenv / copy_env ?

Below is my circus.ini file. Thanks

I moved the question to the circus project as it might be more appropriate place to ask.
