After upgrade to Zimbra 6.0 and now 6.01 having the same problem
system is a CentOS Xen-image: 2.6.18-164.el5xen
taking 2 much cpu-time :-(

Sep 28 17:47:47 mailserver kernel: printk: 27 messages suppressed.

echo "hwcap 0 nosegneg" > /etc/ld.so.conf.d/nosegneg.conf
and ldconfig is NOT working, is slapd using this file ??

ldd slapd |grep libc
libcrypto.so.0.9.8 => /opt/zimbra/openssl-0.9.8k/lib/libcrypto.so.0.9.8 (0x00126000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x00700000)
libc.so.6 => /lib/i686/nosegneg/libc.so.6 (0x00434000)

i did find 2 libs:
/lib/libc.so.6
/lib/i686/nosegneg/libc.so.6
