[389-users] largish member changes causing problems

I am a little perplexed. I am making a change to a groupOfNames object having some 16069 member attributes. I am deleting nearly 16000 members and then adding nearly 16000 members. CPU goes to 100% and never comes down. I have plenty of memory allocated (700MB) to nss-slapd and I have made the adjustments to allow for large objects (maxbersize). I end up having to kill -9 slapd. the annoying thing is some times it works, some times it doesn't. I can't seem to find any common conditions of the failures (or successes). ds = 1.2.9.9 RHEL = 5.7 Thoughts? /mrg
