The issue is due to this upstream commit:
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=f4f2ca1509288f6f780af50659693a89949e7e46
Other possible workarounds are:
- defining the GLIBC_TUNABLES environment variable to
"glibc.malloc.trim_threshold=128"
- changing the kernelvm.overcommit_memory parameter to 1 with "sysctl
vm.overcommit_memory=1"

Aurelien
