[Bug]: Spamming LOG: [ddtrace] [error] Failed sending traces to the sidecar: Os { code: 32, kind: BrokenPipe, message: "Broken pipe" }

Bug report

Hello,

I am currently using this version

• PHP 8.4.2
• Datadog agent version: 7.60.1
• PHP Tracer library 1.6.2

After some time which can vary I get spammed in my logs. I receive thousands of error messages:
[ddtrace] [error] Failed sending traces to the sidecar: Os { code: 32, kind: BrokenPipe, message: "Broken pipe" }

I forced a new deployment of my application and it stopped right now but after some time I just get the same issue again.

Can anyone help ?

Hello @doctenahasib,

Is your application running in a serverless environment?
If yes, could you please set the DD_SPAWN_WORKER_USE_EXEC=1 environment variable.
If no, could you please set DD_TRACE_LOG_FILE=/some/path/ddtrace.log and DD_TRACE_LOG_LEVEL=debug? There should be some information inside about the cause of the broken pipe then.

[doctenahasib]

@bwoebi Yes I am using AWS ECS Fargate.

For now the error disappeared after I did a new deployment. When the issue appears again I will try your solution.

[doctenahasib]

@bwoebi It happened again. I will deploy a new release with the env variable DD_SPAWN_WORKER_USE_EXEC=1 and see if that helps.

[doctenahasib]

@bwoebi DD_SPAWN_WORKER_USE_EXEC=1 did not solve the issue.

[bwoebi]

@doctenahasib Then, could you please install 1.6.3 and set DD_TRACE_LOG_FILE=/proc/1/fd/2 (this should make the log output of sidecar go to the container log) and DD_TRACE_DEBUG=1.
This may contain useful information for getting to the root cause.

@bwoebi I installed 1.6.3. I also enabled the debug logs but it generated so much logs that I had to disable it again because of cost.
However what I found out is that when we have a spike in our cpu and/or memory than we get this datadog tracer issue otherwise not. Could it be that when the tracer crashes that it can not recover from itself ?

Our team has been running tracer v1.6.3 when we first started seeing this issue. Our dd agent was behind so we updated that to the latest version. We tried bumping resource requests, but no matter what the log comes back.

[ddtrace] [error] Failed sending remote config data: Os { code: 32, kind: BrokenPipe, message: "Broken pipe" }

It can appear almost immediately or take as long as 40 minutes to appear, but it always come back.
