openldap-server buckles under load due to file descriptor limitย #181
Description
http://www.openldap.org/faq/data/cache/1126.html
OpenLDAP has a hard coded limit limit of 4096 file descriptors. Documentation suggests using the following compile time flag:
env CPPFLAGS="-DOPENLDAP_FD_SETSIZE=8192" ./configure
This should (based on what I'm reading) work at least as far back as 2.2.30. Older versions may need to use the following instead.
env CPPFLAGS="-DFD_SETSIZE=8192" ./configure

I need this back ported to 2017Q4.

Can I confirm this is with the x86_64 set? The code appears to be written such that it ignores the operating system default (which in our case would be 64k and plenty), but it's hard to tell as it depends on include ordering.

Fixed in NetBSD@01a9f8b, will backport to 2017Q4.

openldap-client-2.4.45nb1 is now available for 2017Q4 x86_64.

What about openldap-server?
jperkin commentedon May 3, 2019
The client package provides libldap, which the server links against.

OK, great. That should work.
Thanks!
