Memory issue running Knime 5.4.0 in batch mode under Ubuntu

I’ve been running Knime jobs in batch mode under Ubuntu for quite some time. Previously I run into problem when upgrading to 5.1 as there were a memory issue when running the columnar back end. However, installing libjemalloc2 and setting MALLOCARENAMAX=1 solved this.

However, after upgrading to Knime 5.4.0 it seems there is a new memory issue. When I start Knime I only get the message below before KNIME exits without any further info.

free(): invalid size

Attempting to remove libjemalloc2 and running Knime allows Knime to start, but I get a lot of other error messages related to memory allocation for the columnar back end.

Is there a known issue related to memory allocation in Knime 5.4.0? Are there any possible fixes or workarounds to this except having to get rid of the columnar back end (which is a big job and might cause other problems)?
