[one-users] econe-server problems with 3.2.1

Hi Ulrich

Those in the log are not error messages but log messages. If you take
a look they log a HTTP 200 return code (SUCCESS). process in 0.8 secs.

Could you confirm the times accessing directly the econe-server... We
believe this is a configuration issue, as we can not reproduce this.
Please also *do not* revert the patches from Daniel

Thanks

Ruben
