we have run into a problem when printing Gantt charts with PDF Gen. They can be extremely slow and on following up with Support they have confirmed that this is an issue with Distiller and there is no fix soon. So to get around the issue we tried disabling Gannt charts in MS Project by un-checking Bars and shapes in Gantt views in 3-D' (Tools > Options, View tab) in MS Project
Now we're finding LC does not always pick up the setting. What we have noticed is that sometimes when printing to PDF with the same file, on the same server via PDF Gen, Gantt charts will appear, and sometimes not. Occasionally, the MS Project file when printing Gantt charts will stall in the Adobe Printer Queue, LC will then start to get Stuck Threads in Weblogic, and basically become unstable.
Upon further investigation we saw that LC will use the WINPROJ.exe if it is running to do the conversion, or start a new WINPROJ.exe process if none is running. Sometimes while starting the process we get the Gantt chart setting picked up, and sometimes not, and there is no particular pattern.
We did a lot of digging with PROCMON to see if we could find if LC was picking up a Windows Registry entry for MS Project perhaps with a different user which did not have the Gannt chart turned off, but could not find one. Our conclusion was that sometimes LC has submitted the job before WINPROJ.exe is fully loaded and somehow the No Gantt charts option gets lost, though this is speculation based on observation of behaviour.
Anyone know what is going on?
