Out of memory when fetching all entities via the API #563

Closed baszoetekouw closed 9 years ago

baszoetekouw commented 9 years ago

Yesterday, this worked just fine:

curl -v -u user:pass 'https://serviceregistry.surfconext.nl/janus/app.php/api/connections.json

to fetch all entities from Janus. Today, I get only a 500 http error :(

The error log is enlightening:

Jan 20 15:16:36 prd43 Apache-SR: [Tue Jan 20 15:16:36 2015] [error] [client 145.97.21.119] PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes) in /opt/openconext/OpenConext-serviceregistry-5.0.1/simplesamlphp-1.12.0/modules/janus/vendor/symfony/symfony/src/Symfony/Bridge/Doctrine/ContainerAwareEventManager.php on line 88

I'm not sure what all 134MB of memory is used for, but all (~1000) entities should easily fit.

Note that fetching of individual entities, either by eid or by entityid, works fine. Therefore, this is not very urgent, I guess.

Can you verify this against the "4th set"? Would be interesting to know if the changes in 1.20 contributed to solving or mitigating this memory hog problem.

baszoetekouw commented 9 years ago

Ah, seems to work ok on the fourth set! It's quite slow though, but that's to be expected, I guess.

So it will likely be better after the deploy of janus 1.20.2 today, and even further addressed when 1.20.3 makes it to production.
