[Samba] smbclient 2.2.5 segfaults on Solaris 7 x86 (long article)

Wed Jul 17 15:25:02 GMT 2002

i'm running samba on solaris x86 only for accessing NT shares. samba is 
not running as a domain master or anything.

the problem is that when i try to upload 18mb file to NT share, 
smbclient crashes.

$ smbclient //<box 1>/<share A>
added interface ip=x.x.1.30 bcast=x.x.255.255 nmask=255.255.0.0
Domain=[ACCORD] OS=[Windows NT 4.0] Server=[NT LAN Manager 4.0]
smb: \> put backup.tar
putting file backup.tar as \backup.tar Error writing file: SUCCESS - 0
SUCCESS - 0 closing remote file \backup.tar
smb: \> Segmentation Fault - core dumped

it starts uploading the file, the upload progress goes _very_ slowly and 
then it crashes.

sometimes it manages to upload 3mb, sometimes even less. it takes about 
two minutes to upload the 3mb.

i need you to help me locate where the problem is. i suspect the problem 
is within my solaris x86 box, because using another solaris 7 sparc and 
samba 2.2.5 with the identical configuration (i checked with 
*testparm*), i can upload the same file just fine.

my configuration:
  share A on box 1 (nt 4.0)
  share B on box 2 (nt 4.0)

  solaris 7 sparc running samba 2.2.5
  solaris 7 x86 running samba 2.2.5

  x86 --uploads 18 mb file--> share A 	[upload is very slow. segfaults]
  x86 --uploads 18 mb file--> share B	[OK]

  sparc --uploads 18mb file--> share A	[OK]
  sparc --uploads 18mb file--> share B	[OK]

here's a stack trace from the core dump:

(gdb) bt
#0  0x08063fed in readline_callback ()
#1  0x080a4d47 in smb_readline ()
#2  0x080640bc in process_stdin ()
#3  0x0806476d in process ()
#4  0x08065e37 in main ()
#5  0x0805f76f in _start ()

*testparm* output on solaris 7 x86 (it's identical to solaris 7 sparc):
