What version of Go are you using (go version)?

$ go version
go version go1.17.8 linux/amd64

Does this issue reproduce with the latest release?

This is the latest release. It reproduced on older 1.17.2 as well.

What did you do?

Clone any package with a go.mod file, and try to go mod tidy it. Eg.

git clone https://github.com/pascaldekloe/jwt.git
cd jwt
go mod tidy

What did you expect to see?

No error.

What did you see instead?

runtime/cgo: pthread_create failed: Resource temporarily unavailable failures. With a package with no dependencies, the failure rate is quite low. With a package with many dependencies, the failure rate is 100%.

This suggests I'm close to a thread limit, but it doesn't seem like it:

My home directory and software installation is on a shared drive, and doing the exact same thing on other virtualised machines on the network is and has been fine for years (the issue isn't limited to go mod tidy, but also go build etc). I'm encountering this issue for the first time on a new machine on the network, which is "bare metal", but has been set up the same way as the virtualised machines with ansible. So same version of GCC AFAICT.

More problematic, other users on the same "bare metal" machine don't have the issue, suggesting there's some issue that is specific to my environment, but that should be the same on all machines.

I'm trying to figure out what the difference and cause is, but nothing obvious presents itself.

This problem went away by itself after doing a fresh login to the bare metal server, so I closed the issue.
Then it started happening again after another fresh login.

The only thing that changed was that ansible altered some things on the server, but it isn't obvious why those changes could result in this issue.

Any ideas what to look for or how to debug?

[heschi]

This is much more likely to be a problem with your machine's setup than an issue with Go itself. You may want to look at some of the resources listed in https://github.com/golang/go/wiki/Questions.

[ianlancetaylor]

The error means that pthread_create is consistently failing. I say "consistently" because if pthread_create fails with "resource temporarily unavailable" it is retried up to 20 times, with an increasing delay between each retry. So basically this means that your system is maxed out in some way: it's out of memory, or there are too many running threads, or too many running processes, or something.

This is unlikely to be a problem with the Go language or standard library. It's much more likely to be a problem with your Go program--perhaps it has a memory leak--or a problem with other processes running on your system.

[sb10]

This is unlikely to be a problem with the Go language or standard library. It's much more likely to be a problem with your Go program--perhaps it has a memory leak--or a problem with other processes running on your system.

The "Go program" in question is go mod tidy, so it's not "my" program.

It is also not an issue with the physical machine per say. It can't be an issue with too little memory, too many running threads or too many running processes, because I have a tmux session running on the machine from yesterday where go mod tidy works 100% of the time, while a fresh login to the same machine gives a 100% failure rate for go mod tidy.

So it's some kind of environment setting that triggers the issue, but taking a diff of go env and ulimit -a doesn't reveal anything significantly different between the 2 different sessions on the same machine that aren't also shared by another machine where it works.

Lots of other people are using the affected machine, and no one else is reporting issues with it. I don't have issues running any other software in my fresh login session to the machine. The only thing suffering from the issue is go, hence the bug report. Is there any way I can debug further?

[ianlancetaylor]

Thanks, I didn't understand that it was go mod tidy that is crashing.

I would start with simply running top or a similar program while running go mod tidy on a different terminal, and see what it is doing. Another step might be stace -f -e clone go mod tidy and see how many threads it creates. These would just be to understand the scope of the problem.

[sb10]

The go mod tidy call completes pretty quickly, so most of the time top doesn't show it running, but here's where I managed to catch it. top was running on a terminal from my tmux session, go mod tidy was running from my fresh login session. (I wasn't able to do the reverse and catch a successful run of go mod tidy in the tmux session; I think when it's successful it's faster.)

From the fresh session where it fails:

$ strace -f -e clone go mod tidy -compat=1.17 2> out
$ grep -c attached out
65

Complete output is here: https://pastebin.com/9m4Rsf1J

From the tmux session on the same machine where it works:

$ strace -f -e clone go mod tidy -compat=1.17 2> out
$ grep -c attached out
62

Complete output is here: https://pastebin.com/Ry8RW9Wc

The numbers vary on both on repeated runs, but typically in the 50-70 range. Same when grepping for 'clone'.
