bblfshd is eating 200% CPU without requests after heavy load

Question

bblfshd is eating 200% CPU without requests after heavy load

vmarkovtsev opened this issue 5 years ago · comments

I've extracted many, many UASTs in 48 threads within the last 4 days. All the clients finished, finally. After several hours, I logged in the machine and watched bblfshd process consuming 200-220% CPU in top. There are no clients running, I guarantee. docker logs bblfshd is here: https://drive.google.com/file/d/1ZWYotVO9tBPDBsZ07STQDH7gwPmK_rvM

In case you want to debug yourself, ssh 163.172.109.207. @meyskens can provide access.

I you want access to the server, be fast as they will be returned at the end of this month.

@meyskens if that is not too hard - I would take a quick look in order to add more information about the symptoms in here.

@bzz As far as I remember, kill SIGABRT bblfshd should print the goroutine stacks, but also kill the process.

and getting the full list of goroutines in details seems not reasonable, stoped counting after 1500

I think i'm going to trigger a full core dump of the process now ~with GOTRACEBACK, if there are no other suggestions. And indeed, that would kill the process, that is also a PID 1. ~

Done with gdb gcore without killing the process 🎉 3.2G core.1 :)

@vmarkovtsev AFAIK you were using 3-4 machines for this large-scale parse, could you confirm that it's the only one that ended up in this state plz?

Wow, actually @bzz it became even funnier now. Right now on 163.172.109.45 and 163.172.109.60 bblfshd is eating 900% CPU without any reason. I stopped the extraction this morning, but did not check top on them.

@dennwc is there a chance server does not handle closing the connections properly somehow?

Would be happy to provide more information if needed, but seems like we have some clues already to access the situation and just need to dig in bblfshd deeper.

Looks like unclosed GRPC channels... Indeed, my code does not close them on the client side. Each process opens 24 channels and then terminates without explicitly closing. This explains much.

Ah, yes, that would definitely contribute. However, I think that can't be the whole story, since even a load-balancing channel shouldn't have more goroutines than available endpoints (and usually not even that many).

Once we have some of the process-management issues under control, I'd like to revisit how we deal with load-shedding on the server side. I believe servers should almost always have a sensible way to shed load (for example, by early-rejecting inbound requests). Ideally the client should be able to respond to the pushback, but even if it can't it's much easier to debug errors on the client than weird DoS failures on the server.

Can it be because of the numerous dying drivers and unclosed channels to them? 🤔

It could—I suspect both are factors. The kernel should drop the connections for processes that have exited but not been reaped, but there may be something different happening inside docker.

@dennwc @creachadair I seem to have found a reliable way to reproduce this using the latest bblfshd.

Download:

tasks1.txt
hercules - to be renamed to hercules and chmod +x

Setup:

apt install python3-pip
pip3 install ipython tqdm

Run:

ipython

Copy-paste there:

import os
from tqdm import tqdm

!rm -rf boilerplate
!mkdir -p boilerplate
with open("tasks1.txt") as fin:
    %cd boilerplate
    rid = ""
    lines = fin.readlines()
    for seq, line in tqdm(enumerate(lines), total=len(lines)):
        commit, repo = line.strip().split(" ")
        if "llvm" in repo or "linux" in repo:
            continue
        new_rid = repo.replace("/", "@")
        if new_rid != rid:
            !rm -rf $rid
        rid = new_rid
        !git clone --bare git://github.com/$repo $rid
        if not os.path.exists(rid):
            print("failed to clone")
            continue
        %cd $rid
        try:
            parents = !git rev-list --parents -n 1 $commit
            parent = parents[0].split(" ")[1]
        except:
            continue
        finally:
            %cd ..
        if len(parent) != 40:
            print("failed to get the parent from", parents)
            continue
        with open("commits.txt", "w") as fout:
            print(commit, file=fout)
            print(parent, file=fout)
        result = !../hercules --typos-dataset --feature uast --commits commits.txt $rid
        print(result[:10])
        if result and result[-1] != "TyposDataset:" and "hercules:" in result:
            with open("new_%s_%d.json" % (rid, seq), "w") as fout:
                ri = result.index("hercules:")
                print("\n".join(result[ri:]), file=fout)
    !rm -rf $rid
    %cd ..

Leave it running for ~30 minutes or less. Then stop (ctrl-z), ctrl-c will not work.

Yes, we are waiting for an Enry release to cut a new bblfshd release. We can cut it before that though.

👍 indeed, let's not wait for enry if that is not crucial for the fix

I don't think this happens anymore, I have processed 70% of PGAv2 and never had problems with this.
