Full_Name: Amit kumar singh Version: 2.4.44 OS: CentOS release 6.9 (Final) URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (14.141.104.38) Issue on replication and get below error. Nov 30 17:03:55 host slapd[709]: connection_read(346): no connection! Nov 30 17:03:55 host slapd[709]: connection_read(346): no connection! Nov 30 17:03:55 host[709]: connection_read(362): no connection! I was searching issue and found that fixed ref: ITS#6548 on 2.4.27. But strange thing is that it comes up again in 2.4.44. Not sure If I am correct but need your help to look into it.

LMDB was originally written for use on 64bit CPUs, with 64bit virtual address spaces. It expects to map an entire DB into virtual memory using a single mmap call. Obviously this cannot be done when trying to use a DB larger than 2GB on a machine with only a 32bit virtual address space. When using MDB_VL32 to access a 64bit DB on a 32bit CPU, the DB cannot fit into a single mmap. It must be mapped in chunks, and the chunks must be mapped, unmapped, and remapped on demand. The rpages thus need to be tracked, to know which are currently mapped. None of this rpage tracking exists in the native non-VL32 build because it's completely unnecessary. Also note that the MDB_VL32 feature is not officially released. You're free to use it if you want, but there is no expectation that it is suitable for general use. When you use unreleased features, you're expected to know how to support yourself. When you use LMDB at all, you're expected to know how virtual addresses work. Ideally, you should quit using obsolete 32bit CPUs. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Yes. Best is to use mdb_txn_reset/renew instead of txn_abort. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Could you maybe explain a bit about rpages? Why does mdb_cursor_close need to unref pages, but not mdb_cursor_renew? If closing a transaction does not clean up rpages, I would have expected mdb_cursor_renew would have to do. And why does setting MDB_VL32 affect rpages in the first place? To my understanding, MDB_VL32 is about using 64 bits also on 32 bit CPUs, so a differences on page handling seem surprising at first sight.

(ITS#8778) Phone numbers "-" and " " fail normalization
by h.b.furuseth＠usit.uio.no 26 Nov '17

26 Nov '17

Full_Name: Hallvard B Furuseth Version: 2.4.45, master OS: Linux x86_64 URL: Submission from: (NULL) (193.90.52.167) Submitted by: hallvard telephoneNumberNormalize() fails for a non-empty value of only spaces+hyphens. The validate function, printableStringValidate(), succeeds. They should agree. I'll make Normalize return one space. That seems the minimal change.

Does that mean it's not trivial to fix and will take some time? It's a last outstanding issue for a release, so I guess we have to find a work around until it's properly fixed? Thanks, Markus
