Re: openldap 2.4.43 keeps crashing

[Leander Schäfer <info@netocean.de>]

I expirience the very same on FreeBSD since quite some versions already 
- in fact since 2010. I had to develope a workaround which is a 
monitoring script. It starts the service again everytime it died. The 
root cause could never be found. Please find the link below for further 
information:
