This bug is created as a clone of upstream ticket: https://fedorahosted.org/389/ticket/47577 Steps: 1) setup up 2 way MMR 2) make sure the entry cache is full, so that search requests must evict old entries from the cache to make room for new entries 3) generate an ADD load against one of the masters 4) repeatedly search for (objectclass=nsTombstone) from the base suffix
Steps to reproduce: 1) setup one instance of directory server with suffix dc=example,dc=com 2) Use ldclt like this to add a lot of entries: ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \ -e add,person,incr,commoncounter,noloop \ -r1 -R1000000 \ -n8 \ -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \ -q & 3) sleep 120 to allow some entries to search/mod/del 4) Use ldclt like this to do a lot of modifies: ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \ -e incr,commoncounter,attreplace=sn:valueXXXXXXXXXX \ -r1 -R1000000 \ -n8 \ -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \ -q & 5) sleep 30 to allow mods to progress 6) Use ldclt like this to do a lot of deletes: ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \ -e delete,incr,commoncounter,noloop \ -r1 -R1000000 \ -n8 \ -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \ -q & 7) use ldclt like this to do a lot of searches: ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \ -e esearch,incr,commoncounter \ -r1 -R1000000 \ -n8 \ -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \ -q & You should see a crash within 10 minutes or so
