 Dear  Andrew:
    
    We've been trying to test our environment as recommended in the last 
posts. We switched the backend to openLDAP trying to discard the idea of 
a bug in eDirectory. And here... the conclusion:
    
    
    Backend switch:
    
    
    1) Sadly, Samba server still getting overloaded. The server doesn't 
hang as in the previous scenario, but it gets extremely slow and there's 
no way to provide service with it (load grows up to 60 or 70). It stops 
responding a couple of minutes after the load gets to the limit.
    
    2) There's an incredible amount of smbd childs in "D" state 
(uninterruptable sleep), when the load starts to raise. It happens with 
both backends (it's softer with openLDAP, but still unusable).
    
    3) The number of sleeping processes is considerably lower with openLDAP.
    
    It seems that, something is beating the samba server because of a 
bug perhaps, or a misconfiguration. The system is a little (but not 
much) tolerant when openLDAP is used as backend (instead of eDir), but 
the problems still no matter the directory service being used.
    What do you think about a client triggering this behaviour some way?
    
    
    Weird things found:
    
    I'll comment some lines about a couple of strange things i saw. They 
may be completely unrelated to the main problem, but here they go just 
in case.
    
    1) Some times (according to what an strace attached to the parent 
smbd process shows us), a user working on an XLS file starts a curious 
behaviour in which the server tries to find a file that no longer exist 
in a periodically basis (i.e: loop). We think the user deleted the file, 
still an smbd process kept trying to access it. (it was complaining with 
"file does not exist" messages permanently) (A few minutes later when the loop 
was happening we went to the user desktop and found out he has already turned 
off his machine!)
    
    We've captured service logs, straces, ps aux snapshots during the 
load issue and a couple of lsofs.  (The whole samba's logs are more than 1G 
and is impossible to determinate a fail, because the server still responding 
until the load is too high to continue serving files)
    
    Is there any way to get some more verbosity? any different way of 
debugging (gdb maybe?)?
    
    Thanks in advance
