Colin Patrick McCabe commented on YETUS-286:
--------------------------------------------
We now we have some C++ code in the tree whose build time is drastically
reduced by using a higher concurrency level. Typical maven builds don't peg
the CPU because maven spends a lot of its time downloading things from the
internet, writing files, running unit tests, and so on. gcc processes also
don't use a lot of memory when compared to maven (most of the time). So I'm
skeptical that running make -j 16 will be that harmful in practice. We could
certainly look into tuning this, but I don't see why it would be the root cause
of "failed to map segment from shared object" failures.

> Key: YETUS-286
> URL: https://issues.apache.org/jira/browse/YETUS-286
> Project: Yetus
> Issue Type: Bug
> Components: Test Patch
> Affects Versions: 0.2.0
> Reporter: Colin Patrick McCabe
> Assignee: Sean Busbey
> Priority: Critical
>
> On Jenkins, the native build seems to intermittently fail with "failed to map
> segment from shared object." For example:
> {code}
> [WARNING] /usr/bin/cmake: error while loading shared libraries: libxml2.so.2:
> failed to map segment from shared object: Permission denied
> {code}
> We have also seen this happen with {{librtmp.so.0}}, {{libcurl.so.4}}, and
> other native libraries which are dependencies of the thing being built.
> Basically, there is some random chance any particular native dependency will
> get "failed to map segment." When this happens, the native build fails and
> returns a -1 even if there was no actual problem. This requires us to re-run
> Jenkins to get a correct result. The problem does not seem to reproduce
> locally.
