On Sunday, I did a "yum update" which installed kernel 2.6.32-573.3.1.el6.i686 on half a dozen virtual machines running CentOS 6.7. Since then, two of them have gone into "meltdown", and started spewing "ABRT Daemon" emails: one on Tuesday, and one tonight. The machines have a very light workload -- one runs "trac", and a handful of development systems, for a small team of developers. The other is primarily a git repository. So, aside from housekeeping jobs, both machines are more-or-less idle. Both machines generated SEVERAL HUNDRED "ABRT Daemon: a crash has been detected again" email messages in something over an hour. (That said, one of the two machines sent a (single) "crash detected": it had the same "missing module" error message, but only one message was generated) I include a sample message below. When I logged on to the machines when they were in "mailing frenzy", the only processes that "top" showed me using any CPU were "sosreport" and "abrtdaemon". They seemed to be vying for "top spot". In each case, I rebooted the machine, and all is now calm. But I am worried that it will affect other, more "visible" ideas. So, Q1: Is this a known problem? Q2: And how do I stop this happening again? Roll back to a previous version of something? Disable abrt? What?
