Greetings, and thanks for your report! GCL based applications probe brk at runtime to determine an upper bound for its permissible heap. Running under strace -f is usually helpful to see if your kernel messages are correlated with this loop. To my understanding, if brk triggers a 'no enough memory for the allocation' condition, it should simply return an error code to the user space process, and not generate any kernel level difficulties. brk just reserves the memory, and does not actually allocate it until it is written, so no oom machinery should be involved.
