Host 3766033 and host 4302067 are using 2.4L builds without any weakly similar comparisons AFAICT. That suggests there's nothing fundamentally wrong with the builds. Perhaps the issue is some minor incompatibility with certain versions of Linux or perhaps the two hosts with problems have some weaknesses. The 2.4L builds have been in use for months, I cannot believe any major problem would have gone unnoticed this long.
