>>Also how would I know that *now* in 2.4.19 all problems are fixed and >>the answer next week won't be: You need to use 2.4.20. Testing reveals the presence of bugs, not the absence :) So no one can every say version x.y.z is certified bug free. However, I do tend to agree, in that my MM just flaked out, and there is not much load/write/update going on so I am a bit worried. I am not trying to put down OpenLDAP but iplanet/fedora directory server/389 support up to a 4 way MM implementation and I have found the replication rock solid even under high load. So if MM is your requirement that may be a more valid option. >>The answer is quite simple: do not use multimaster replication in a >>production environment. In most cases the requirement for multimaster >>replication is just based on poor directory design. Dieter, I do not agree with that. You can't blame a user for using a feature. It is not marked as experimental anymore so people are going to use it. Once it fails you can't call them a "Poor Directory Designer" for using it. http://www.openldap.org/faq/data/cache/1240.html
