Hmmm... FWIW, we've compiled some more info to illustrate the problem. Starting w/a sniplet from the Solaris 10 "fopen" man page, test programs showing the "difference" between open and fopen calls under Solaris, a postgres log file w/extended logging and a diff-file of that fd.c to show how the addt'l logs were produced. I hope this makes it somewhat clearer, i.e. no system-wide, but a per-process topic and related to that Solaris 32-bit ABI backwards compatibility... surely not a world-wide problem, one would agree. Nevertheless, we'd though it prudent to at least mention it. Btw, here's what Oracle has to say: http://www.oracle.com/technetwork/server-storage/solaris10/stdio-256-136698.html I hope the 15K attachment gets through... cheers, hardy Hartmut Raschick Network Management Solutions ----------------------------------- KEYMILE GmbH Wohlenbergstr. 3 D-30175 Hannover, Germany Phone: +49 (0)511 6747-564 Fax: +49 (0)511 6747-777 mailto:hartmut.rasch...@keymile.com http://www.keymile.com << KEYMILE - because connectivity matters >> Geschäftsführer/Managing Directors: Björn Claaßen, Michael Breyer, Axel Föry - Rechtsform der Gesellschaft/Legal structure: GmbH, Sitz/Registered office: Hannover HRB 61069, Amtsgericht/Local court Hannover, USt-Id.
