I saw this same behavior with hhvm 3.1 a few months ago but when I upgraded my server to VM with more memory and CPUs the problem stopped happening.  I am seeing it with hhvm 3.3 with some smaller/older instance types (< 2GB main memory, and <= 2 VCPUs).  This is a pre-built package running under Apache2 (fast CGI) on an Ubuntu 14.04LTS platform.  I don't know why, but the stacktrace files that I'm getting (example below) don't have anything in them after the URL line.  Is there a way I can collect more information for the team?\r\n\r\nroot@ip-172-31-16-215:/tmp# cat stacktrace.2730.log \r\nHost: ip-172-31-16-215\r\nProcessID: 2730\r\nThreadID: 7ff2e67ff700\r\nThreadPID: 2734\r\nName: unknown program\r\nType: Segmentation fault\r\nRuntime: hhvm\r\nVersion: tags/HHVM-3.3.0-0-g0a3cfb87b8a353fc7e1d15374f4adc413e37aba9\r\nDebuggerCount: 0\r\n\r\nThreadType: Web Request\r\nServer_SERVER_NAME: ec2- ***.compute.amazonaws.com\r\nServer: ec2- ***.compute.amazonaws.com\r\nURL: /***/\r\n\r\n"}}
