A wild guess is that fbserver.exe (SuperServer) is busy doing something (costly report/processing, long-running query, sweep etc.) and by nature can only utilize max. one CPU/core per database. During that time, others are stuck or even can't connect. I have seen this many times in various support cases now with SuperServer. Switching to Classic (SuperClassic) and some fine-tuning usually helped a lot, especially on a SMP server. -- With regards, Thomas Steinmaurer http://www.upscene.com/ ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Resources item on the main (top) menu.
