Hi

Error 14 is EFAULT. It means that pread is given invalid buffer address. Why? I don't know. I need to debug the application.

First of all please try to rebuild IMCS from scratch. May be you first build it without IMCS_DISK_SUPPORT and then with it. So please do make ... clean all install

If it doesn't help, I really need to debug it Can you attach debugger to postgres, set breakpoint on line 90 of fileio.c and print stack together with values of local variables. Or may be you can provide me SSH login to you system, so that I can debug it myself...
