HHVM 3.18 deadlocks after 4-6 hours (stuck in in HPHP::Treadmill::getAgeOldestRequest() )
Closed, ResolvedPublic

Description

After serving requests on mw1261 for 4-6 hours, HHVM deadlocked reproducibly (three times so far). Back traces below. There are previous occurances of that error with 3.12 as well, which were logged in SAL, but with 3.18 it happens _much_ more frequently:

Event Timeline

I suspected this might crash due to our setting of kernel.perf_event_paranoid=3 and some kind of resource leak due to failing perf_event_open() calls, but after setting kernel.perf_event_paranoid=0, mw1261 still crashed after approx seven hours.
I saved the new back traces and will depool mw1261 for now, otherwise it'd flap again in a few hours.

I'm building our internal HHVM extensions against the HHVM packages provided by Facebook, to gather an additional data point

MoritzMuehlenhoff triaged this task as High priority.

After further debugging I now believe that stat_cache is still broken in 3.18 and causing these deadlocks. To confirm, I've disabled the cache on mw1261, it's running without deadlock since about five hours now and if that holds throughout the evening I'll report back to upstream with latest backtraces.

mw1261 is stable with stat_cache=false for ten hours of production traffic now. I've reported this back to upstream along with an updated backtrace of a deadlocked thread.

T89912: HHVM lock-ups has some related clues, specially a debugging session T89912#1286874 which mentions concurrent_hash_map and the StatCache holding a lock

For this task stack trace that would be:

...

And I mentioned it somewhere else, the statcache got enabled via T75706. At the time that has cut system CPU by half.

The current performance loss seems less significant though (e.g. compare mw1261 with HHVM 3.18 and stat_cache disabled to mw1266 with HHVM and stat_cache enabled in Grafana's server dashboard). The machines are identical hardware-wise.

IIRC, the biggest performance hit was on the API cluster, where we get more requests per second. I'd test a API host too.

This has been fixed upstream, I'm currently building a new package (and also rebasing to HHVM 3.18.2 while at it) to validate the fix.

This seems fixed, it hasn't deadlocked with live traffic for approx 18 hours \o/ CPU and memory consumption are also stable. I'll upgrade the remaining canary servers and let it run over the weekend before proceeding with a wider rollout next week.

@MoritzMuehlenhoff I'm ok with a wider but limited rollout, but at least until the dc switchover and rollback are done, I'd prefer to stick with the known evil of 3.12 on most systems.

Marking this one as fixed, the dead lock hasn't reoccured. The rollout of the new packages will be handled via the parent task.
