Thanks everyone for the responses. I tried out the JeMalloc suggestion from FLINK-19125 using a patched 1.11.3 image and so far it appears to working well. I see it's included in 1.12.1 and Docker images are available so I'll look at upgrading too.
Best regards, Randal. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
