According to kernel source, this function makes buffer with whole path. This stack trace indicates that path was too deep, so trace happened on buffer overflow. Additionally, this stack trace happens on controllers with mongodb. To mitigate it, I suggest
1. Try to deploy 100 nodes without mongo
2. Upgrade mongodb to 2.6.5 where it has redesigned file system algorithms. Also it has many bug fixes related to file system
