The logs for my Cloud Dataflow job contain multiple messages of the form:

[GC (Allocation Failure) [PSYoungGen: 72352K->160K(71168K)] 120584K->48392K(158720K), 0.0022739 secs] [Times: user=0.00 sys=0.00, real=0.00 secs]

What does this mean? What should I do about it?

The "Allocation Failure" message is a completely normal part of Java memory management; it just means the JVM has run out of memory and needs to trigger a GC. Unless there is already a reason to suspect memory problems, the "Java GC" log is generally not worth looking at for Dataflow pipelines.

Please see Java GC (Allocation Failure) for additional information.
