I have workarounded the situation by reconfiguring all 3 thousand domains to share the same log files, and use the split log scriot which comes with apache under support/ directory, as a guy has recomended me on freebsd list. However, I feel that sooner or later I will find out the same limitations again. And when I get close to 7 thousand domains I will certainly start having the same problems. So I need to know how to deal with this, because CPU and memory are resources that I will not starve soon. I have raised max files per proc and kernel maxfiles to unbelieveble values. This is the way to deal with this lind of limits in FreeBSD. However it did not help, so I think there may be some other kind of resource I am not raising. BTW I could out I can use EXTRA_FLAGS as argumento to make, make EXTRA_FLAGS=-DFD_SETSIZE=8192 resulted in FD_SETSIZE=8192 getting passed to Apache on every compilation line. But it did not help minimizing the problem. So, yeah, maybe this FD_SETSIZE thing is only for apache before 2x. Anyway this is a problem I think people will always have when they run some number of VirtualHosts. I dont think I am the only one here who have thounsands domains in a single Apache enviroment. BTW I have found this same limitation earlier with recent Linux kernel, but it was a 800 domains limitation. I had raised the appropriated values as suggested in a number of readings (including Apache2 documentation) and I got no solution. So I switched to FreeBSD, and only by setting maxusers kernel parameter accordingly I was able to have 2.8k domains. Now I found the same limitation again. But this time I doubt I can switch to anything else. I am sure this is something that need to be tunned up now and probably could have been tunned up earlier on Linux. So I need to understand what kind of resources Apache may starve, up to the point it stops responding or simply dies with error code 11. I am sure it is a resource thing because when I removed all that many log files, things started to work again, perfectly, and in fact with better performance. However, it is a resource problem which I havent fix, because I dont understand correctly what else, other than fd's Apache needs, so I can raise it. While I have free memory and free CPU cicles I intend to keep adding VH's to apache. So I need to learn to surpass this software limits. Hope people here in this list can help me.

I don't remember for sure, but I don't think that FD_SETSIZE has any effect in 2.x. You just need to make sure that your OS has allocated the necessary file descriptors to apache before you start.
