I got the debug info this time. Whenever I restart a stuck replica it is crashing the master. Hope the following will be helpful.

Hi Ulrich,

Quanah helped to build one with debug and not stripped.

Thanks, Suresh

Hi!

I don’t know the details of the build process, but sometimes RPM strips the binaries. Otherwis you could look for strip or a corresponding option in the Makefiles.

I used "make STRIP="" install" but it still installed the stripped version. I understand your suggestion. I don't have the appropriate access on my end to install Symas packages. I can only install the ones I build with a prefix limited to /var/services directory.

Thanks, Suresh

I downloaded the src - openldap-apkg26.tar.gz, removed the optimization flags (export CFLAGS='-g'), configure, build and install, but still installed the stripped version. Am I missing something?

[root@aaa-dev-gcp-1 libexec]# file slapd slapd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=547e20101751207ad48cc96006ea51e7610c7a1c, for GNU/Linux 3.2.0, stripped

This is basic software building, but:

make STRIP="" install

I still suggest using the Symas packages over building things yourself.
