Could you please cross-check that with ldapsearch reading that particular entry? Nevertheless slapadd should not crash. Rather an error should be reported. But please try to reproduce the issue with a recent release (at least 2.4.19, preferrably CVS branch OPENLDAP_REL_ENG_2_4). Another option would be to provide sanitized test data to let others try to reproduce it. Ciao, Michael.

This is a little odd: (gdb) run -d 255 Starting program: /usr/sbin/slapd -d 255 must compile with LDAP_DEBUG for debugging *** "CRASH" *** Program exited normally. (gdb) ba No stack. I have been running a script, while ldapsearch -x; do sleep 10; done, that eventually crashes slapd. But gdb provides little feedback, as noted above. >> One things to note is that, in addition to being on MIPS32, my platform >> has only 32MB of memory.

I have just reconfigured slapd to use one thread and removed all indexes from the configuration. So far, I have not seen a crash. I am no using two clients to query slapd and have removed that sleep statements so that the server is continuously queried. I've been running this for about one hour and will report back if there are any negative results.

Doesn't it? Based on my *very incomplete and possibly wrong* analysis, the problem would be automatically cured by using back-bdb. Also, fixing back-hdb *if it's broken at all* should be possible. p.

It sounds reasonable to me :) But unless you are not in any way allowed to - ever - make writes to more than one server in a mirromode setup, this could (as I hear it) potentially happen at any time. The only reason I have to only make writes to one server is that I currently (this will change) have an application which is dependant on making writes and immediately reading back the entry. As I hear what you're saying is that any write to a server in a mirrormode setup could invalidate a slapcat running on the other. This would mean that you can never write to more that one server at all and that's the only server you can slapcat while running. That takes a lot of the "mirror" out of "mirrormode". Doesn't it? >> If I can't trust slapcat during this >> phase, how can I trust slapcat for backups? > > Does slapcat behave this way on the active server? I've taking that test setup down now to test other stuff, so I can't say 100%. /Peter

If the problem is as Ando suggests, then it's because in the syncrepl Refresh phase it's receiving entries out-of-order from the provider. Ando is suggesting that the problem is caused when a child entry is replicated before its parent. Once the Refresh phase ends and it transitions to the Persist phase, all entries' parents will exist and so this particular condition will no longer occur. Of course, no one is saying for certain that this is the explanation, yet. > If I can't trust slapcat during this > phase, how can I trust slapcat for backups?

However, there's one server which is used for application access and to minimize disk load on that server, the plan was to take most backups from the other. I can't see any difference between what you call "initializing" and normal running state, except that the difference between server-1 and server-2 is (somewhat) larger. If I can't trust slapcat during this phase, how can I trust slapcat for backups? /Peter

(ITS#6376) memleak in 2.3

Full_Name: Matthew Backes Version: 2.3 only OS: any URL: Submission from: (NULL) (76.88.99.93) In 2.3, if you have a lot of fast writes such that syncprov_sendresp's op tmp memory is exhausted and it has resorted to malloc()s AND controls are asserted, the rs.sr_ctrls free at the end of the function leaks. To duplicate: Set up a master and a replica. Do mods like crazy with some control asserted, e.g. manageDSAIT. 2.4/head handle this differently so it isn't a problem there.

You appear to be using back-hdb. I note that in bdb_tool_entry_get() there is code specific to back-hdb that tries to lookup the parent of the current entry and, if found, "fixes" its DN. My guess is that if this can fail, e.g. because entries are being sync'ed out of order, the DN does not get fixed. If this is the case (I couldn't inspect code deep enough to make sure), I'd expect that the DN get fixed anyway, though, because missing entries should exist as "glue" objects. I apologize for the rather incomplete analysis, I can't dig further right now. I hope this provides some hint to others, unless completely wrong. p.

For us everything seems OK but PineApp appliance just can't authenticate with our replica. PineApp refuses to give us further help saying that something is wrong in LDAP replication. Please, could you help us with that issue: the replica has the same information that master server has? We thank OpenLDAP Team in advance. Best regards, Jose Oliveira
