As soon as I open a doucment using Office Web Apps, I have three process that starts to take all the CPU.
The three processes are
C:\Program Files\Microsoft Office Servers\14.0\WebServices\ConversionService\bin\Converter\AppServerHost.exe.
There's nothing particular in the ULS logs.
What can I do to troubleshot the issue ?
PS: Don't know if it can help, but it's a demo computer running on the same box a W2K8 R2 OS, with AD role, Sql 2K8R2, SP2010 server enterprise (all possible services started, except foundation search and lotus connector) and Office Web apps.
