This is probably the somewhat braindead Solaris STDIO library
biting you. It cannot cope with FILE * pointers if the underlying
fd number opened is over 256 (it uses an unsigned char for the
fd member of the FILE struct).

This is why tridge wrote the XFILE library for HEAD (3.0). I
believe there are replacement stdio libraries for Solaris that
don't have this problem but - try forcing Samba to link with
something like "sfio" for example.

Does anyone know when Solaris will fix this problem ?
