Directory Server no longer logs false `attrlist_replace` errors
Previously, Directory Server could in some circumstances repeatedly log `attrlist_replace` error messages in error. This problem was caused by memory corruption due to a wrong memory copy function being used. The memory copy function has been replaced with `memmove`, which prevents this case memory corruption, and the server no longer logs these error messages.

Hi Ludwig, Could there be verification steps for this bug? Just do cleanallruv, and if we don't see "attrlist_replace - attr_replace (nsds50ruv, {replicageneration} 56012d2f000000040000) failed." message in the error log, we could say the fix is verified? Thanks! Hi Noriko, there are two requirements to trigger the bug. - the RUV needs to contain a lareg number of RIDs, I have seen this with 9 replicas - the RID to be cleaned should be in the beginning of the replica list in the ruv (position 1 is always the local RID), so the RID on pos 2 or 3 should do. so if you have a RUV like: nsds50ruv: {replicageneration} 51dc3bac000000640000 nsds50ruv: {replica 200 ldap://localhost:5200} 5609f0a4000000c80000 560e0886000000c80000 nsds50ruv: {replica 100 ldap://localhost:5100} 5609deae000000640000 560e0970000100640000 nsds50ruv: {replica 500 ldap://localhost:5500} 5609f0a4000000c80000 560e0886000000c80000 nsds50ruv: {replica 400 ldap://localhost:5400} 5609deae000000640000 560e0970000100640000 nsds50ruv: {replica 600 ldap://localhost:5600} 5609f0a4000000c80000 560e0886000000c80000 nsds50ruv: {replica 700 ldap://localhost:5700} 5609deae000000640000 560e0970000100640000 nsds50ruv: {replica 800 ldap://localhost:5800} 5609f0a4000000c80000 560e0886000000c80000 nsds50ruv: {replica 900 ldap://localhost:5900} 5609deae000000640000 560e0970000100640000 nsds50ruv: {replica 300 ldap://localhost:5300} 5609f0a4000000c80000 560e0886000000c80000 then clean rid 100 and don't see the message the fix is verified 6 master replication.
