Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I'm trying to get the following utilities to compile, but have been encountering errors. I suspect that my build environment is not correctly set up. I am trying to compile the programs on a standard Mac OS X 10.4.4 system. I downloaded all source tarballs from Apple's Darwin sources page. I am trying to build these tools with the same configuration as they shipped in 10.4.4, except with debugging symbols and possibly no optimization. The tools: as (from cctools) - gives errors that seem to be related to i386 thread structures not being defined vim (from vim) - complains about typedefing typedefs zsh (from zsh) - rlimit.c: RLIMIT_RSS and RLIMIT_AS seem to have the same value, and conflict in switch statements This email sent to site_archiver(a)lists.apple.com

Out of curiosity, I have been checking out the thermal profile of my new Quad within the IO Registry and the kernel source code. In doing so, I've noticed that "CPU B PUMP" does not appear in the IO Registry, even though it is listed in the Info.plist file for the platform plugin. Is this normal?

I've started to try to make this "one Question" to dts so I can use a technical incident to solve it. The problem is (I've been in touch with dts many times) is how to "define" this bug. That the reaason I turned to this list, as everybody I spoke to pointed here, and told me that this is the place if you want to know how to find out things that buried deep into Darwin. What I wanted was to know how I can get a accurate list of processes usage of system resources (fd:s is one of them) so I can tell Apple something like "Why is Java eating all those filedescriptors with this piece of code"? If I cannot put it tis simple, it wont be one question, and it wont fit into the "one question per incident" formula. Right now, I'm suggesting that if you ask that "one question" you will have wasted it unless your hypothesis happens to be correct. Sorry if I sound to hash, but everybody seems to look at this as "it impossible, it cannot happen", but ask me, I can give you DL instructions and my crash samples, and you can see four your self how bad this issue is". I'm not denying for a second that you have a reproducible crash case; merely attempting to direct you down a path that will get it resolved. When you spoke with Apple Sweden about this issue in the first place, did they give you a bug number? If you have a test case that reproduces this bug, please file a bug report with that test case. If it's as reproducible as you're describing, you almost certainly won't get it tossed back to you as being impossible. If you do, or if Apple.se filed a bug in order to get this investigated in the first place, please post the bug number to this thread so that we can look at it. = Mike _______________________________________________ Do not post admin requests to the list.

We suspected HW problems, we even got a new XServe and send the old one for repair, but we experienced the problem on the otehr box too (other model), and then I made it happen. The last thing in the system log usually is: Jan 14 15:57:19 tor DirectoryService[41]: NetInfo connection failed for server 127.0.0.1/local then nothing, in any logs... Thats why I suspect out-of file descriptors, as all other possible solutions are gone, or, its a driver level bug in OSX 10.4.x (that doenst exist in the 10.4.3 build for intel (DTK) where this runs flawless with the UB build. Sadly, these sorts of problems are rarely so simple. As Arnie once said, "It's not a tumor!". = Mike _______________________________________________ Do not post admin requests to the list.

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I still don't understand why you think that the above is caused by a file descriptor leak. There is simply no evidence whatsoever to support that assumption. However, all that being said, if you were to have mentioned, for example, which particular "DB server" you're using, what the workload for it is, and how the remainder of the system is configured it might be possible to reproduce the problem and determine what is actually going on. Since you're determined that it's a descriptor leak of course, you haven't done that. You'll get best results overall from describing the problem you're having, and including the above information so that an engineer can reproduce the actual problem on a machine in front of them, and putting it all into a bug report so that Apple can actually take a look at it. Since you have a DTK system you should have an ADC account, and so getting some attention for your bug shouldn't be too hard. This email sent to site_archiver(a)lists.apple.com

I don't see any reason for making this assumption, other than perhaps "because that's what makes Linux hang like this", "that's what makes Windows hang like this", or "that's what someone in the elevator said it must be". = Mike _______________________________________________ Do not post admin requests to the list.

Hard freezes like the one you're describing are typically caused by hardware problems or device driver bugs. This email sent to site_archiver(a)lists.apple.com

This only happens on the live, business critical machine, not any test machines of cause. HW ruled out, happens on two different HW, when delegated as main production server.
