Drooped bay to the RedHat "OEM" samba-2.2.3a-6 RPzms.  Same exact problem.  I'm
becoming a bit frustrated,  and no one else on the list seems to be experiencing
this...

What exact kernel version are you using? version of glibc?
Did you get the problem by *just* upgrading to 2.2.5 or did you up levels on
anything else?

There has to be a common component we have.

[root at sardine root]# ldd /usr/sbin/smbd

If I use lsof I can see all the files it has memory mapped (which should include
all loaded libraries) -

Nothing really stands out as a likely candidate. :(
