Re: [Hypercontent-users] Is this a bug , workflow takes time to load

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

This is likely the cause of the delays you are seeing; the system  
must be able to acquire a lock on workflow scripts in order to  
initialize them, so you have to make sure that once you open a  
workflow script for edit, you save or discard your changes.  If you  
leave the file open the system will time out trying to acquire the lock.

After things have gotten weird with the workflow components, its also  
a good idea to restart the server.  This won't clear the lock,  
however - you can manually remove that from the filesystem by looking  
for "/config/workflow/build.xml/file.lock".

Cheers,
Alex
