The current plan is to fix this in OpenLDAP 2.5, and we are now halting new
development in 2.4.

As per ur suggestions,tried changing
1. MDB_PAGESIZE to 65536
2. changing pb_lower and pb_upper to uint32_t.
As of now it is running fine for the existing testcases in
openldap-2.4.36. However there were problems in 2.4.35. Also saw the
comments in openldap-devel. So whether this will make to openldap 2.4.36?

Yes, your test config shows that the problem is that rwm_conn_destroy frees
the session context while rwm_op_search is using it. Seems like the rwm
overlay is not doing reference counting properly.

It is not the client loop that is multithreading but the ldap server.
And it is not a misuse of the API but a problem that may be raised by day t=
o day network problems.
I've boiled down the problem to a few simple configurations that work (or b=
etter, fail ;-) with both 2.4.23 and 2.4.36. A tgz file containing a setup =
with start script and testclient is attached. It should be sufficient to re=
produce the fault.
The problem occurs only if we use session variable substitution in the rwm =
overlay, and only if a search is *immediately* (e.g. caused by network loss=
and client timeout) followed by an unbind.

(ITS#7725) LMDB readahead should be configurable
by hyc＠OpenLDAP.org
Full_Name: Howard Chu
Version: 2.4.35+
OS: Linux
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (78.155.233.73)
Submitted by: hyc
In 2.4.35 (commit b1da555c4c7275d7f756d693c42814388a9aa839) code was added to
unconditionally turn off readahead, because it is harmful to random read
performance when a DB is larger than RAM and/or system RAM is already full.
Unfortunately turning it off harms sequential read performance. It should be
configurable, since different behaviors are needed in different use cases.

> Sorry - here's the stack trace:
Which backend were you testing, it's not shown in any of your output. Your
trace is strange because it shows overlays being used, but test005 doesn't use
any overlays. Seems like you may have a slapd left over from some other test.
