-----BEGIN PGP SIGNED MESSAGE----- Hello, the following problems I wrote yesterday has been partly resolved now: > I've installed Apache 2.2.3 on a Redhat Advanced Server 4 (with all > updates installed).

Thus I do no longer need to try compiling Apache with --without-ldap.

But I did not yet see problems correlating to this message.

This problem also did not longer occur after starting the "nscd". I had installed Apache 2.2.3 on many hosts at the same time, those problems that now disappeared only occured on hosts that were running up-to-date GPFS servers at the same time (but not on those that only were GPFS clients). I cannot imagine how GPFS service can interfere with the name resolution, but obviously it happens. Thanks to all who were willing to help me. cu - -- Rainer Perske, Zentrum für Informationsverarbeitung, Universität Münster Lesetipp: <http://www.textkritik.de/schriftundcharakter/sundc008tofu.htm> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (AIX) iQDVAwUBRRE7/89UbnbjB8C5AQEyaQYAqFlTxS0qcGmHqroVCJxl11mXi/tZyPZ6 bMisCwZ1IKHB2LbeRShD5Rx9Ve4nmaHLL7r7z+0lGLbuCsbOBKY3pk297s/jCYpv siZb3BatHKE3vrk/RuUEm+EFSNOBWrM/ag0iSUhJoSGgAyJcjw0cETR+Pb7bz9BP Ioo/pBZU850CpjAKeFwjDacAUeWNN42YEbg82i8Jp5Vyp5krk7E2q1ZsRVFDA2tb C/Efo1tH7uj1zhiv/xMpoJ9owYZphkIT =koPh -----END PGP SIGNATURE----- --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
