Re: [Babeldoc-devel] [babeldoc - Help] multiple Babeldoc processes

[Bruce M. <br...@mc...>]

David / Davor:

If your are running two instances of babeldoc (two jvms) then all is good - 
the simple journals steps do not get mixed up.  The problem arises when you 
are threading, in the same pipeline for the same journal ticket, then the 
ticket steps get mixed.  

The issue is that the simple journal uses the strict consecutive provision of 
ticket steps to know about ordering, etc.  This is a problem if you have 
multiple threads - everything is out of order...

regards,
Bruce.
