[Samba] smbd/oplock_linux - Failed to setup RT_SIGNAL_LEASE

[P K]

Getting this all over my logs for all my client PCs.  All on Windows XP Pro
Clients running on samba 3.0.20a PDC.    Kernel 2.4.22.
 
[2005/10/19 00:03:48, 0] smbd/oplock_linux.c:linux_init_kernel_oplocks(295)
  Failed to setup RT_SIGNAL_LEASE handler
 
Not sure if this is a kernel or samba issue?  Also clients are complaining
about random drops of there word documents etc....I'm not sure but may be
attributed to this?

  read_data: read failure for 4 bytes to client 192.168.2.22. Error =
Connection timed out
 
Anyone know what this one means?
 
Thanks so much in advance!!
