In order to solve this problem I am looking at upgrading my version of fedora-ds which is : fedora-ds-1.0.4-1.RHEL4 to the latest version which is 1.1. Is there anything I need to look out for in this kind of upgrade ?
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/accessmay 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.
Thank you in advance.
