Jeremy,
I think we found the part of source where the problem resides:
smbd/trans2.c
+1444 for (i=0;(i<maxentries) && !finished && !out_of_space;i++)
{
+1445 BOOL got_exact_match = False;
+1446
+1447 /* this is a heuristic to avoid seeking the dirptr
except when
+1448 absolutely necessary. It allows for a
filename of about 40 chars */
+1449 if (space_remaining < DIRLEN_GUESS && numentries >
0) {
+1450 out_of_space = True;
+1451 finished = False;
+1452 } else {
+1453 finished = !get_lanman2_dir_entry(conn,
+1454 inbuf, outbuf,
+1455 mask,dirtype,info_level,
+1456
requires_resume_key,dont_descend,
+1457 &p,pdata,space_remaining,
&out_of_space, &got_exact_match,
+1458 &last_entry_off);
+1459 }
+1460
+1461 if (finished && out_of_space)
+1462 finished = False;
+1463
+1464 if (!finished && !out_of_space)
+1465 numentries++;
+1466
+1467 /*
+1468 * As an optimisation if we know we aren't looking
+1469 * for a wildcard name (ie. the name matches the
wildcard exactly)
+1470 * then we can finish on any (first) match.
+1471 * This speeds up large directory searches. JRA.
+1472 */
+1473
+1474 if(got_exact_match)
+1475 finished = True;
+1476
+1477 space_remaining = max_data_bytes -
PTR_DIFF(p,pdata);
+1478 DEBUG(5,("call_trans2findfirst - space remaining
%d numentries %d\n", space_remaining, numentries));
+1479 }
at line 1478 we added an extra debug line to see what's going on.
with every file the space_remaining is going down from 16384
(max_data_bytes) to 0 in varied steps of 100 till 150 bytes.
just before the out of space error we see the following:
space_remaining=4 bytes or something like that. And at the same time
numentries=121

So the next time that get_lanman2_dir_entry is called there is not enough
memory to put in the next entry.
Every time this out of space error occurs we can see that the file is
called with get_lanman2_dir_entry, but is not send to windows.
Then the function call_trans2findfirst goes further with the remaining
files and run well till the space_remaining is too low again and then
another file is lost in the dir output.
We also notice that maxentries=1644 and max_data_bytes=16384. maxentries
appeared to be calculated. But I could not found out so far
how max_data_bytes was calculated. Can this be increased? Or could it be
that DIRLEN_GUESS is too small?
So my idea is that in AIX 5.2 ML5/6 + latest fixes the number of bytes used
for direntries consumes more memory that in linux.
Can you help us further with this?

Talk to James Peach at SGI. I'd like to get him to reproduce your
problem on IRIX before I think it's a Samba problem.
He's on the mailing list archives.
Jeremy.
