Not configured to run any job that is queued. The instance is configured with more Sidekiq workers, but most of the extra workers are Read more about running multiple Sidekiq workers. Runs one worker, restricting the execution of Sidekiq jobs to a maximum of one CPU core. By default, a single-node Linux package installation The GitLab instance may need more Sidekiq workers. Symptoms of slow Sidekiq performance include problems with merge request status updates,Īnd delays before CI pipelines start running. Investigating Sidekiq queue backlogs or slow performance In GitLab 13.5 and earlier, set SIDEKIQ_LOG_ARGUMENTS to 1 to start logging arguments passed to Sidekiq. Workers where their arguments are not sensitive. GitLab logs numeric arguments for all workers, with overrides for some specific To avoid logging sensitive information (for instance, password reset tokens), Some arguments passed to Sidekiq jobs are logged by default. Preventing other threads from continuing. May be using all available CPU, or have a Ruby Global Interpreter Lock, This may mean there’s contention in the database, for example,īut look for one thread that is different than the rest. Thread appears to be waiting in the database, Redis, or waiting to acquireĪ mutex. In any of the backtraces, be wary of suspecting cases where every It may reveal a bug or necessary improvement in GitLab. GitLab administrators/users should consider working through theseĭebug steps with GitLab Support so the backtraces can be analyzed by our team. Troubleshooting steps to help you diagnose the bottleneck. May not show up and merge requests may not be updated. Users notice when this happens because new branches Situations also tend to be high-pressure because a production system job queue When things go wrong it can be difficult to troubleshoot. Sidekiq is the background job processor GitLab uses to asynchronously run CPU saturation in Redis caused by Sidekiq BRPOP calls.GitLab 14.0 and later: remove the sidekiq-cluster service (Linux package installations).Clearing a Sidekiq job deduplication idempotency key.Remove Sidekiq jobs for given parameters (destructive). Investigating Sidekiq queue backlogs or slow performance.
