Re: max open files

Hi Alex,

I think this falls into the "you get what you pay for..." camp.
On the support page, they list a number of companies that provide
technical support services for OpenLDAP. If the price for stability
is not worth engaging one of them, then you will need to keep your
software up to a revision level that the developers will support.
I am curious what constant issues/bugs are affecting you. Once we
have a working version, it keeps on working and there is no need
to constantly rebuild your software as new releases come out. The
other option that we use here is the 389 Directory server, which
might be an option for you to consider.
