hello all,

I upgraded to OpenLDAP 2.4.43 three weeks ago. It runs on debian squeeze
64bits lts
it is built from sources with the fix from ITS#8330

Since the upgrade, it keeps crashing regularly (I would say once every
2 to 5 days)
However, there isn't anything in the logs: no message, no error, no
nothing

slapd no longer runs, I restart it, and it runs ok until the next crash

now I don't know how to debug that.
I could downgrade to the previous version (2.4.41) which worked fine,
but as our university is closed until 01/11, this is the perfect time to
investigate. I still don't know if it's a bug in 2.4.43 or a
misconfiguration for which previous versions was forgiving

What are your advice to track down the cause for the crash?

PS: here is a bit of context:
one master with 2 mdb databases: one accesslog, one for the data
two slaves (I mean complete replication, even cn=config)
the master has crashed only once
the slaves keep crashing regularly
the slaves are complete replicas of the master, and I wonder if it
could be a source of problems: I'll give details in another thread
Do you have accesslog purge configured?

I ran into this on an accesslog purge with 2.4.43:

http://www.openldap.org/its/index.cgi/Software%20Bugs?id=8336;selectid=8
336

If you start slapd with '-d 1', you should be able to see if it is the
issue.

The fix referenced in that ITS worked for me.
hello,

thanks for the response.
no, purge is not configured, but this is a nice suggestion... without
purge, I guess the accesslog database would keep growing forever :-(

Yes, you generally want to configure a purge interval.

David,

Why haven't you reported this to the ITS?
