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. > The native build randomly fails with "failed to map segment from shared > object" > ------------------------------------------------------------------------------- > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
