The default KVA/UVA bance changed recently in the RELENG_4 branch, and this caused the Linux threads mailbox location negotiated between the kernel and user space to change. This was "fixed" in 4.8-RELEASE, but it was fixed in a way that lets you move KVA_PAGES up and down, but it is not binarily compatible. You probably need to relink MySQL against the new Linux threads library, which probably means recompiling both the library port and MySQL. -- Terry
