This might be a bug ..
samba/smbd/service.c
617 init_structs();
618
619 if (!reload_services(False))
620 return(-1);
init_structs eventually has file_init() called, which uses
Globals.max_open_files to set real_max_open_files, a static
int in smbd/files.c.
The problem is that Globals.max_open_files is only set to
MAX_OPEN_FILES by init_globals, which is first (and only?)
called through reload_services(), the result is that
smbd/files.c:real_max_open_files is set to 0.
Surprisingly enough, on my system isn't stopping files being opened,
probably because the limit is set to maxfiles+FUDGEFACTOR and I'm not
using it in a large system, but it does cause a problem in the call
to file_new(), which has the calculation:
64 first_file = (getpid() ^ (int)time(NULL)) % real_max_open_files;
Since real_max_open_files = 0, the daemon dies of an Arithmetic Exception.
This was causing my roaming profile problem, and probably some others that
I was ignoring.
