dptr_create: returned 9: Error - all new dirptrs in use ?

[Franz Sirl]

Uhm, this seems to be a dptr leak in combination with Win98/Win98SE. In a 
Win98  command window try "dir L:\support\mga*." (note the trailing dot) 
with "L:" being a samba-2.0.5 share and "support" a directory with 8.3 
files like "mga?????.bak", but no files like "mga?????". You'll get 
something similar to this end of the output with debuglevel=3:

And whoops, one dptr got lost here, as you can see if you issue another 
"dir L:\support\mga*.". Win95 doesn't show this behaviour, I haven't tested NT.

I'm not sure if this is a bug in Win98 or Samba. As our application is 
scanning the directory every few seconds, this dptr leak locks up the smbd 
a few times a day. I'm currently testing a workaround using "mga?????" as a 
mask which doesn't seem to leak dptrs.

On a side note, during debugging I got a 500MB (!) logfile, even though the 
maximum size is set to 1 MB. It seems the rotating doesn't work well at 
higher load.
