Full_Name: Thomas Bopp Version: 4.2.22 OS: Solaris 10 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.47.255.100) After approximately one week our LDAP stops working and hangs (we had this situation several times). We have the www.sunfreeware.com package of LDAP installed. It had a bunch of connection in CLOSE_WAIT state (indicating basically that a close request has come in but slapd did not serve it). Making a truss on the process showed all threads blocked on lwp_cond_wait. I really need a solution for this problem.

Hi Quanah! sorry for the wrong release, I meant 2.4.22 of course. /Thomas -------- Original-Nachricht -------- > Datum: Wed, 16 Feb 2011 16:34:39 GMT > Von: quanah@zimbra.com > An: openldap-its@openldap.org > Betreff: Re: (ITS#6833) LDAP hangs on Solaris > --On Wednesday, February 16, 2011 11:37 AM +0000 tombolala@gmx.de wrote: > > > Full_Name: Thomas Bopp > > Version: 4.2.22 > > > I really need a solution for this problem. > > I suggest you list an actual OpenLDAP release.

Yet with identical code, no such hangs were reported on Solaris 9 or Solaris 11. I suspect there's a bug in the implementation of select() on Solaris 10, causing it to fail to report the connection close events. Some discussion of this problem occurred in this email thread http://www.openldap.org/lists/openldap-devel/201101/msg00033.html Try 2.4.24, and try a different Solaris release.

Hi! Thanx for your reply. We have been able to reproduce the problem on a test system and found out that setting "idletimeout" seems to fix this issue for us. Note that we enabled gentlehup! We have now the new configuration on our production environment and everything seems stable. We are not able to change solaris versions. If there are still problems we will upgrade the openldap version. On another system we have the same ldap configuration (gentlehup and no idletimeout set) and do not experience any problem.
