I don't think upgrading will solve your problem.

The large number of 2743 (T1) Idle Timeout Exceeded errors is really 
strange.   I think
logconv.pl -V /opt/fedora-ds/slapd-ldap1/logs/access
may provide more information about those connections.  I'd like to see 
what the etime is for those operations.  If those errors really are 
caused by some application just hanging attempting to read from the 
directory server, you might be able to increase the ioblocktimeout 
setting in the server, but that will work only if those operations are 
hanging.
