Modify sysctl's such as net.ipv4.tcp_keepalive_time, 
net.ipv4.tcp_keepalive_intvl, and net.ipv4.tcp_keepalive_probes to be more 
aggressive, so that TCP keepalive might detect the wedged connection.

(I'm assuming Linux based off the RPM-ish version you gave.)


Unless "-8" patches fixes for the DoS issues present in earlier 2.3 
releases, you should give some serious thought to upgrading. At a minimum, 
read a current change log so you can at least evaluate your present 
exposure. Again, with your RPM-ish version, I'd look at Buchan's third 
party RPMs. See the list archives for copious discussion of the dangers of 
using vendor-supplied packages to run slapd.
