Chasing 503 Guru's

[Simon Males]

Just wanted to share my understanding of tracking down 503 / Guru
meditation errors.

Steps:
1. Source the XID
2. Start varnishlog with -d
3. Search the output for the above mentioned XID
4. Hopefully the log entry will provide a clue

Though how long do the shared memory logs exist? Or is it common
practice to write varnishlog to disk in production environments?
