Re: FW: Application Error in slapd.exe on W2000


I'm seeing the same error when I import your ldif.

In bdb_return_entry():servers/slapd/back-bdb/id2entry.c in 'free( e->e_bv.bv_val )' seems to always throw that assert.

The memory content looks valid, so the other explanations are that it's not from the local heap or from the stack (??)

Has anyone experienced the same problems or is it only me?
I tested with the same ldif-file but with version 2.0.23 of OpenLDAP
and it works fine!

Hi to all,

IS it possible that there is a serious memory leak in the server.
I've enabled LDAP_MEMORY_TRACE and saw that the mem in-use is increasing
rapidely untill the server crashes...

Any one any idea?

Thanks,
Geert

Do you have a debug build you can use?  Can you reproduce the error on a
  machine with a debugger?  You may need to run the debug build in MSVC
to get a stacktrace.

OpenLDAP no longer supports Cyrus 1.x builds, IIRC.  Please correct me
if I'm work someone.  OpenLDAP configure complains about all but recent
versions of SASL and some intermittant crashes I came across were
attributed to the SASL library, even if I only used '-x'.  If you don't
need the SASL, try building without it.

I have a similar config as you that seems to work ok.
berkeley 4.0.14, OpenSSL 0.9.6d, back-perl with active state perl 5.6.1.
Those binaries are here.
http://prdownloads.sf.net/acctsync/openldap-binaries-2.1.3-16JUL02.zip
See if those crash as well.  You need activestate perl binaries to run
these though, as they are linked against perl56.dll ( I need back-perl )

Hi,

I've build OpenLDAP 2.1.3 on a W2K system based on
- Berkeley DB 4.0.14
- Cyrus SASL 1.5.24
- OpenSSL 0.9.6d (TLS enabled)
- HS regex-lib

I've tried to import a big ldif file:
(ldapmodify -x -a -D "cn=Manager, c=BE" -w "password" -f x500-names.ldif)

This gives me "sometimes" an application error in slapd.exe and 

"sometimes"

this works!!

After a successfull import, I'm having the same error when performing the
next search:
ldapsearch -x -b "c=US" -D "cn=Manager,c=be" -w "password"
(userCertificate=*)

Leaving out the filter gives me back all entries
ldapsearch -x -b "c=US" -D "cn=Manager,c=be" -w "password"

Here's my slapd.conf


Can someone please help me with this one?
Thanks in advance!

Geert
