We’ve had 2 crashes on 4D Server with the HTTP thread. For us this is a rather higher-volume site.
I’ve seen here 4D v15.4 seems to perform well in this area in particular – it survived DOS attack simulation. We are looking for suggestions and insight. Are there issues with 4D v15.4 that would caution upgrading to it? Thanks!
