[Mono-list] odbc in multiprocessor system

[Glen Ford]

Hi,


Has anyone stuck problems with using ODBC against a multiprocessor 
system?  Our system runs fine on a single core, but when moved to a 
multiple core machine we get crashes under xsp2 with various stack 
traces pointing towards System.Data.Odbc.libodbc (example snippet below)

We are using unixODBC compiled threadsafe and thread-safe Informix 
libraries.

Before raising a bug I thought I would just see if anyone else has 
experienced similar.


Regards,


Glen
