That makes at least two who's got this problem. I do get 503 from time to time, but I've never seen the "hieroglyphs". Also, it does not correlate with HHVM crashes:

Sep 29 10:18 /tmp/stacktrace.1242.log
Oct 3 06:06 /tmp/stacktrace.1631.log
Oct 5 14:01 /tmp/stacktrace.31216.log
Oct 7 05:28 /tmp/stacktrace.10417.log

but most likely it's related to HHVM. I aeady increased the timeout, but possibly it's something else.

When you see that again, please note the time and the URL. I'll try to find something in the logs.

will do!

OK, now I have something to search for. It's something in between Apache and HHVM.

According to one of the troubleshooting posts I've tweaked the config of mod_deflate. Please let me know if there is a difference.

The more I look into it, the less I understand why it works like it works. For some unknown reason, Apache removes "Content-length" header, behaves like it does not know the size of files, and gzips images, regardless explicit denies. But not always, what makes it even more difficult to understand and troubleshoot.

I'm giving up... I tried everything, I was nice and gentle, I even consulted with the specialists, and read the special literature, I put on sexy clothes, but he?... she ... it still ignores me... sniff ... It does not listen to me... I told her it to stop touching the attachments, but it likes to squeeze them tight, even if they are getting bigger afterwards.... What a pervert...
