Londinium Zip How To Go About

Fix bug in 5 minutes that I was hunting for already for 2 hours and no end in sight.

This ought to be fun How does NUMA play into the debugging (Asking because I have no idea.).

You can sendreceive multiple requests, and then close the connection on the last request (using Connection: close).

Youll need to handle cases where the server chooses to close the connection (by simply opening a new connection) etc.

It sounds to me like he doesnt necessarily know which request is the last request - the response to a given request may or may not result in sending additional requests.

If theres a resource thats really cheap to handle on the server side you could use that as sort of a noop.

Connect, do your actual request(s), then request the noop resource w Connection: close.

This, exactly. That was my suggestion (force an echo after we get the final response to close the connection), but my boss wanted me to find out if there wasnt a better way to resolve the issue.

Fira Code has an even bigger set of ligatures, if youre into that sort of thing.

This ought to be fun How does NUMA play into the debugging (Asking because I have no idea.) Just dictates how to go about the investigation.

In our system we have NUMA-aware heap allocation, so there are also 40 heaps.

So if the threads are being good public citizens, they will be affined to a particular core.

I can find which heap got corrupted by the address of the allocation, so I can find the NUMA domain that the culprit should be executing on.

Assuming the thread is still alive, I only need to sift through 125 threads to find it.

IF it is not being a good citizen, and it has not been affined properly, then I have to sift through the other 4875 threads.

This looks like a case of buffer overflow, because the memory fence got blown through on the footer, but the header is still fine.

Time to bust out the fishing pole and see what can be found, I hate fixing other peoples bugs.

Sadly (happily) it continues to run.

Ah.the good old JVM swallowing stacktraces.

Well, damn. I didnt realize this existed.

And that many NPEs being thrown.not so good.

Good luck getting rid of them.
