The first two stacks look normal.

Yes, sorry about that. I later saw that the indexer wasn't really stuck,just very slow, and later recovered.

  The third one may or may not be reasonable depending on what code is being indexed.

What would really help here is an example code file that triggers the hang that we can investigate.

You can "git clone --recursive https://github.com/scylladb/scylla";. Thefile that most often causes the hang is tests/cql_query_test.cc. Thatfile is both very large, and has a large amount of nested lambdas.

There's some setup that needs to be done to get include files anddefines right, or perhaps I can make my settings available. Let me knowwhich files you need.

Nate

Hi, I'm more or less tracking CDT master. Recently the indexer hangs
when processing large files, consuming 100% CPU in one thread.


Using jvisualvm I see it's spending a lot of time here:


org.eclipse.cdt.internal.core.dom.parser.cpp.semantics.CPPVisitor.findDeclarationOwnerDefinition()
6.449319    49,477 ms (6.4%)    49,477 ms    49,670 ms 49,670 ms


I would love to provide more information, but I'm a complete n00b
(or rather, I forgot all that I've ever learned) about debugging
Java applications. If you can provide guidance about what can be
done to provide more information, I'll be happy to dig some more.

I remembered SIGQUIT prints a thread dump, so here's one data point.

Here's a fun one:
