Tuning the ulimit -s down to 10240 solves the issue. That specific machine has a modified limit.conf. I know that with ulimit -s too high, the number of threads that can be created is limited (I'm not sure whether the reasoning applies here). For what's it's worth, tuning the stack size down solves the issue.
