Hi, I have been working with 389 as a potential replacement for Sun DS and I have found it to be an excellent choice in every aspect except the final tests I have been running.
I am running with the current version for RedHat 6, but not the latest from the rmeggins repo: Name : 389-ds Arch : noarch Version : 1.2.2 Name : 389-ds-base Arch : x86_64 Version : 1.2.9.14 I have searched through all the release notes and part of the 389-users list archive for clues as to the possible memory leaks and/or patches in the latest releases, but no information has been forthcoming. The behavior I am seeing is a total memory consumption occurring over a large quantity of ldapmodify operations. To test this, I reduced the size of the directory from 10GB down to about 1.7GB. Then I set up a loop that would run an ldapmodify that would delete of most of those entries followed by an ldamodify that would add all those deleted back in (and then repeat indefinitely). The directory starts out by loading all the entries into the cache and using a few GB of ram to hold everything. Eventually, this loop causes the entire 32GB of ram to be consumed even though the total size of the directory does not change (e.g. currententrycachesize: 1791096898). Replication is enabled to a consumer and the change log is up to 7.4 GB, and it doesn't seem to want to clean out the change log even with short purge times and short entry lifetimes configured, so perhaps something is at issue here. The consumer has processed all updates and also seems to exhibit overconsumption of memory. Are there any pointers related to this? If there is no information about this, is there a documentation page that might instruct me in the correct way to attach valgrind to the ns-slapd process so I can see if there is some kind of huge leak? Thanks very much, Russ. ============================== Russell Beall Programmer Analyst IV Enterprise Identity Management University of Southern California [email protected] ==============================
