Jenkins crashes with OOM when using this plugin

    • Jenkins ver. 1.642.4
      test-result-analzyer plugin: 0.3.4

      Ever since we installed this plugin Jenkins has been crashing with an OOM.
      No settings were tweaked in this plugin (all the defaults have been used).

      I've monitored the memory usage and the moment I click on "Test Results Analyzer", the memory goes up and up and up and then crashes Jenkins.
      (Note: It does not always crash Jenkins though. Sometimes I have to click that button a few times AFTER it has rendered)

      My guess is that the net.sf.json is the culprit. The version is not mentioned in the pom.xml, but older versions of this library had memory leaks, like from this post, back in 2009: link

      Also, the function createJson is sucking up the entire json tree into memory.
      I'm not sure if there is a way to optimize this loop (maybe serialize to disk?), but without putting a profile on that bit of code, I'm pretty sure that is where the problem lies.

      I'm running my master on a t2.medium (4 gigs of ram, almost all of it allocated for Jenkins), and we have around 3K unit tests that run per build. (And by default his plugin goes back 10 builds)

          Same issue here. I have a job running ~8000 tests.
          The moment I click on "Test Results Analyzer", the memory goes up until Jenkins crashes.

          For jobs with a couple of hundred tests it works just fine.

          Looks like I'm running into this as well. Recently my Jenkins instance's memory consumption exploded and the CPU usage has been off the charts as well. Digging into the heap dump I'm pretty sure it's this plugin.
