The combination of translucent and pcache overlays crashes OL or makes it unresponsive. Any attempt to modify an object on the replica by using the following ldif:
dn: uid=joe,dc=foo,dc=com changetype: modify add: description description: first -
dn: uid=joe,dc=foo,dc=com changetype: modify replace: description description: second -
cause OL to fail either during the modification or on the subsequent operation. Specifically, OL behaves differently depending on the type of database backends that are used for translucent and pcache DBs, as it is shown below:
translucent db,pcache db: comment bdb,bdb: freezes on the second modify op bdb,mdb: crashes on the secend modify op (invalid pointer) mdb,mdb: completes the modify ops. crashes on the first search on object mdb,bdb: completes the modify ops. crashes, if not on the first, then on subsequent op
Attached files: a)the cn=config ldif for each of the above cases and b)the corresponding debug output during the modification of the user object or if that completes during the subsequent search on it.
