Thanks @William for the suggestion. I haven't tried strace, I'll look into it, although I've now experienced the crash without the 2 long running processes - so it seems like it may be just the application under load when the varnish cache is first cleared that causes the problem, which is not very encouraging..
@Yann thanks for the pointer, I'll get in touch with the PHP maintainers to see if they've had any similar reports. Thanks again for your time and feedback - much appreciated.
