Hangs or returns 502 bad gateway error #199

Closed wphowell closed 6 years ago

wphowell commented 6 years ago

The site seems very unreliable these days, with lots of 502 errors and/or timeouts; or the following error:

Could not sync loadout with remote: error (). This shouldn't normally happen, try again or refresh the page. Please report if the problem persists.

I have been getting a lot of these today too.

I fixed an issue today in the cache pruning script, it turns out sessions hadn't been cleared for quite some time. The cache directory contained 2.2 million files, 95% of which were useless. No filesystem, no matter how good, handles a single directory with so many files well, which may explain the frequent timeouts, especially today as it took a lot of I/O to remove all the stale files.

Please tell me if the issue keeps happening from now on in the next couple of days.

Seems to be operating perfectly now -- very responsive!

This might just be placebo effect. Don't hesitate to repoen in a few days if you still encounter many timeouts.
