How do you use Sentry?

Self-hosted/on-premise

Version

1.30.0

Steps to Reproduce

Sentry SDK initialised as following:

sentry_sdk.init(
    dsn='...',
    release='...',
    environment='...',
    send_default_pii=True,
    request_bodies='always',
    traces_sample_rate=1.0,
    integrations=[
        FlaskIntegration(),
        StarletteIntegration(),
        FastApiIntegration(),
        SqlalchemyIntegration(),
        RedisIntegration(),
    ],
    auto_enabling_integrations=False,
)

CPython 3.11.5

Expected Result

Hey @decaz, thanks for the report. While we look at this you can set enable_backpressure_handling=False in your sentry_sdk.init(), that should disable the Monitor altogether. Alternatively downgrading to 1.29.2 should do the trick in the meantime.
