Max queue size in Passenger3

[Hidetaka Matsumoto]

Hi,

I want to know the default queue size in Passenger3 like PassengerMaxRequestQueueSize.

( I know PassengerMaxRequestQueueSize is since 4.0.15 )

https://www.phusionpassenger.com/library/config/apache/reference/#passengermaxrequestqueuesize

https://github.com/phusion/passenger/blob/0ef3222e86ede97dff189de1137cca67684d4e2d/src/cxx_supportlib/Constants.h#L57

When I updated Passenger 3 to 5, I saw many 503 errors as bellow.

[ 2016-09-04 06:55:05.9337 1830/7f5b5d0a5700 age/Cor/Con/CheckoutSession.cpp:269 ]: [Client 2-35262] Returning HTTP 503 due to: Request queue full (configured max. size: 100)

before: Passenger 3.0.11

after: Passenger 5.0.30

(use with Apache2)

The root cause is our database slow query, I know.

But I wonder why our system could work much less 503 with Passenger 3.

Anyone know the default queue size in Passenger3?

Thanks.

Sorry, it is too many years ago to remember. It might even have been unlimited (0).
