WAAE 11.3.6 SP7 on Linux + Oracle

The encountered problem was related to a known problem in Linux Kernel.
The same flaw that was introduced to the RHEL 7 kernel 3.10.0-514.26.1.el7.x86_64 was also ported to the RHEL 6 kernel 2.6.32-696.3.2.
The solution documented by RedHat is to upgrade the RHEL 6 kernel to version 2.6.32-673 or higher.
The workaround documented by RedHat is to increase the Java stack size by setting "-Xss2m" in the Java startup parameters.
For the System Agent, that means adding the following parameter in “agentparm.txt” file:
