Solaris fcntl CPU/Lock update

[Jeff Mandel]

I have followed this fcntl bug closely, and I just applied a T-patch for 
solaris 8 which brought the kernel 108528-19. This includes the fix for 
4735093. This has not fixed the problem of smbd growing to consume all 
available CPU.
Environment is SunOS reiger 5.8 Generic_108528-19 sun4u sparc 
SUNW,Sun-Fire-280R
nss_ldap-203
pam_ldap-137

Here's an excerpt of the truss I've used to diagnose this with sun.

Any suggestions?
