The following issue has been CLOSED ====================================================================== http://www.dbmail.org/mantis/view.php?id=682 ====================================================================== Reported By: m2000 Assigned To: ====================================================================== Project: DBMail Issue ID: 682 Category: Authentication layer Reproducibility: always Severity: minor Priority: normal Status: closed target: Resolution: unable to reproduce Fixed in Version: ====================================================================== Date Submitted: 14-Feb-08 21:45 CET Last Modified: 05-Oct-08 12:18 CEST ====================================================================== Summary: IMAP/LMTP dies when LDAP disappears, even if it comes back a minute later. Description: This seems to be another repeat of bug http://www.dbmail.org/mantis/view.php?id=612, but reproduced in 2.2.7 and 2.2.9.
This seems to happen to us about 1 to 2 times a day (but sometimes doesn't happen for a week), wherein we get the following error: Feb 13 09:06:33 perch dbmail-imapd[12984]: Error:[auth] authldap.c,auth_ldap_bind(+130): ldap_bind_s failed: Can't contact LDAP server Around this time, no one is able to establish new connections to IMAP, and all LMTP deliveries cease. The only known fix is to stop the dbmail-lmtp and dbmail-imap services, and then restart them. ====================================================================== ---------------------------------------------------------------------- m2000 - 28-Feb-08 20:15 ---------------------------------------------------------------------- We found out why the LDAP fails (an internal problem involving DHCP + duplicate IPs), but not why DBmail freaks out afterward and does not recover w/o a restart. At this point I have a perl script that reads the dbmai.err file, and if it sees the right string, restarts dbmail. However, this is not a good long-term solution. ---------------------------------------------------------------------- paul - 28-Feb-08 22:11 ---------------------------------------------------------------------- The problem is I can't reproduce this, but perhaps my test is not representative for your problem. Could you please provide level=5 logs and steps to reproduce. ---------------------------------------------------------------------- m2000 - 28-Feb-08 22:15 ---------------------------------------------------------------------- I'll try to reproduce it this Saturday (maintenance window already scheduled) ---------------------------------------------------------------------- m2000 - 02-Mar-08 04:23 ---------------------------------------------------------------------- Ok, I now should have some logs for you, however I need to audit them first and redact any proprietary/personal data from them first. I'll get them to you probably by Monday (Pacific/US time) ---------------------------------------------------------------------- m2000 - 03-Mar-08 21:37 ---------------------------------------------------------------------- Putting some work into it, I'm afraid that there is practically nothing from trace level=5 Mar 1 18:53:57 perch dbmail/imap4d[4370]: Error:[auth] authldap.c,auth_ldap_bind(+132): ldap_bind_s failed: Can't contact LDAP server Mar 1 18:53:57 perch dbmail/imap4d[4370]: Error:[serverchild] serverchild.c,PerformChildTask(+303): could not connect to authentication Mar 1 18:53:58 perch dbmail/imap4d[4372]: Error:[auth] authldap.c,auth_ldap_bind(+132): ldap_bind_s failed: Can't contact LDAP server Mar 1 18:53:58 perch dbmail/imap4d[4372]: Error:[serverchild] serverchild.c,PerformChildTask(+303): could not connect to authentication Mar 1 18:53:59 perch dbmail/imap4d[4374]: Error:[auth] authldap.c,auth_ldap_bind(+132): ldap_bind_s failed: Can't contact LDAP server Mar 1 18:53:59 perch dbmail/imap4d[4374]: Error:[serverchild] serverchild.c,PerformChildTask(+303): could not connect to authentication Mar 1 18:54:00 perch dbmail/imap4d[4376]: Error:[auth] authldap.c,auth_ldap_bind(+132): ldap_bind_s failed: Can't contact LDAP server Mar 1 18:54:00 perch dbmail/imap4d[4376]: Error:[serverchild] serverchild.c,PerformChildTask(+303): could not connect to authentication Mar 1 18:54:01 perch dbmail/imap4d[4378]: Error:[auth] authldap.c,auth_ldap_bind(+132): ldap_bind_s failed: Can't contact LDAP server Mar 1 18:54:01 perch dbmail/imap4d[4378]: Error:[serverchild] serverchild.c,PerformChildTask(+303): could not connect to authentication Mar 1 19:14:12 perch dbmail/imap4d[4255]: Debug:[server] server.c,server_run(+291): MainSigHandler(): got signal [15] Mar 1 19:14:12 perch dbmail/imap4d[4257]: Message:[server] pool.c,manage_stop_children(+475): General stop requested.

However, I do not know if the bug in dbmail has been fixed. ---------------------------------------------------------------------- paul - 05-Oct-08 12:18 ---------------------------------------------------------------------- I'm closing this bug since I'm unable to reproduce it.
