The probable fix is not in a released version - it will be in the next one. Please try to upgrade to the latest and then replace postgres.exe with the one from http://blog.hagander.net ad let us know if it works in your situation. > >> In these cases their .NET app returns this error >> Exception of type 'System.OutOfMemoryException' was thrown > > That's probably a bug in their application caused by failure to properly > handle a connection problem. Yes, or possibly npgsql having the bug, though I haven't heard of it there. The stacktrace should probably tell you where - if not, a memory dump with the debugger. /Magnus -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
