+`LTTNG_UST_BLOCKING_RETRY_TIMEOUT`::
+ Maximum time during which event tracing retry is attempted on buffer
+ full condition (millliseconds). Setting this environment to non-zero
+ value effectively blocks the application on buffer full condition.
+ Setting this environment variable to non-zero values may
+ significantly affect application timings. Setting this to a negative
+ value may block the application indefinitely if there is no consumer
+ emptying the ring buffer. The delay between retry attempts is the
+ minimum between the specified timeout value and 100ms. This option
+ can be useful in workloads generating very large trace data
+ throughput, where blocking the application is an acceptable
+ trade-off to not discard events. _Use with caution_.
++
+The value `0` means _do not retry_. The value `-1` means _retry forever_.
+Value > `0` means a maximum timeout of the given value.

+Default: {lttng_ust_blocking_retry_timeout}.
