Don't know about those library errors... could be you need check and fix paths in /etc/ and rerun ldconfig. Have not needed to mess with that though on SLES 11.

Some questions to get a better feel of the environment SLES is running in/as:

Which VMware version are you running there (version/build) en which VMware tools version (also was this a tar install or rpm).

I'm also curious to know how these SLES servers have been setup (which version is it? The VMware release and 32 or 64bit) and did you add any special parameters into the boot options?

Lastly, what are these servers doing? Which software is running and maybe some custom tuning has been done?
