Martin, the latest i have been able to get out of OL support are these 2 things.

1) Limit the # of Alambics that are able to run (Preferences,Messenger). That helped a little, but not much.

2) Set a Dos Run Plugin right before any PDF Image creation objectin the process tree and have it run the following command.

taskkill /f /im ppalmbic.exe

That seems to have done the trick. Although it does generate(at least on my system) a few Recoverable errors. I get a few Alambic Crash errors, but they are flagged as recoverable and the Alambic restarts and completes the job.
