Hello. I didn't know that pastes from rafb.net are removed after 24 hours. The new location of thread dump is here: http://www.sulechow.net/~mwaldows/ITS-5280/thread-dump.log and new location of JLDAP debug is here: http://www.sulechow.net/~mwaldows/ITS-5280/debug.log Regards Marcin M.Waldowski(a)sulechow.net wrote: > Full_Name: Marcin Waldowski > Version: novell-jldap-devel-2007.10.12-1netware_windows > OS: Windows XP > URL: > Submission from: (NULL) (83.20.102.205) > > > Hello. > > Our application gets lots of information from LDAP server which uses refferals. > Code which use jldap is executed in single thread.

(ITS#5280) JLDAP waits for response for request which hasn't been sent because of connection shutdown

Full_Name: Marcin Waldowski Version: novell-jldap-devel-2007.10.12-1netware_windows OS: Windows XP URL: Submission from: (NULL) (83.20.102.205) Hello. Our application gets lots of information from LDAP server which uses refferals. Code which use jldap is executed in single thread. After some time of obtaining informations JLDAP hangs in MessageAgent.getLDAPMessage() as you can see at following thread dump: http://rafb.net/p/kwhTyh67.html It is repeatable every time we execute our application. It hangs always in the same line of JLDAP code. We turned on jldap debug (-Dldap.debug=TraceAll) and also sniffed communication between JLDAP and LDAP server using Wireshark. Interesting part of JLDAP debug you can see here: http://rafb.net/p/diqKzz11.html As you can see some refferal connections is lost in lines 14, 35, 53. After that we have some writes to that connections in lines 240 (message 146), 283 (message 147) and 333 (message 148). All this writes didn't come to the wire (as we can see in Wireshark or rather cannot see) because of "java.io.IOException: Output stream not initialized". This exception is only logged to debug stream and silently discarded in com.novell.ldap.Connection.writeMessage(LDAPMessage msg) because variable clientActive is false. So, If I understand it correctly, caller code doesn't know that anything goes wrong in called (write message) code. As a result JLDAP still wait for responses of messages 146, 147, 148 which hasn't been sent. This ends up with forever wait in line 368 of debug stream. Regards Marcin

Re: (ITS#5273) ldap.conf and TLS as a default

This appears to be the same as ITS#5039. This ITS will be closed, you can followup to #5039. cardoe(a)gentoo.org wrote: > Full_Name: Douglas Klima > Version: 2.3. > OS: Linux > URL: > Submission from: (NULL) (216.155.111.10) > > > I was looking for a way to make TLS the default in > /etc/openldap/ldap.conf however it currently seems impossible.

(ITS#5283) translucent search enhancement

Full_Name: Howard Chu Version: HEAD/RE24 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.91.220.157) Submitted by: hyc Currently the translucent overlay only searches the remote database, then matches local entries to the results. It needs to be able to search the local database as well.

(ITS#5282) refreshAndPersist can miss changes if error occurs
by quanah＠zimbra.com 13 Dec '07

13 Dec '07

Full_Name: Quanah Gibson-Mount Version: 2.3.39 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.21.80.71) If one is using refreshAndPersist with syncrepl, and an error occurs during a change, the contextCSN will not be updated. However, if a /new/ change comes in after that, that is successful, the CSN will be updated, and the missed change is lost. This can happen, for example, if the replica runs out of locks while making the change. It would be best then, if this happens, for the replica to drop out of persist mode. This is a good reason to set an interval with this mode.
