"signal 11" indicates either a hardware problem (e.g. bad RAM) or a bug in
the software. In this case it is probably the latter. You'll need to
diagnose and fix that bug.

Best option would be to capture a core file and examine a stack backtrace.

This is an openldap issue, rather than a bug in runsv.
