so you want to come over and spend a few days resolving dependancies? :-)

Wireshark/tcpdump?
That may at least give you an idea as to where it goes off the rails.

That was my response.
Strace or whatever your local equivalent is.
I find 99% of aborts are internal failures such as attempting to open a missing file, port, pipe, etc, which are not checked or result in a bullshit error message. Days of tech support back and forth or 20 seconds in strace. Always use strace to start.

caveate, not on a prod box during prod time, strace can knock a box over
I know that you know that, just put it out there for anyone else not familiar with strace "Science is the belief in the ignorance of the experts" – Richard Feynman

Actually, I didn't
Well, unless you attach to a kernel process then trigger a deadlock, but I just made that up.
References please.

You use the term differently than I do
Knock a box over is to cause a panic.
I know strace will dramatically slow the app I am tracing, but it is already aborting and I need to find out why. If it is due to a non timing related issue, then it doesn't matter. If, in a worse case scenario, it causes the target to lock hard, be unable to be run again while the previous instance is locked which means you need to reboot, that would come close, but that is different from an unanticipated panic.

yes, did not mean cause a panic and a kernel crash but making a system unresponsive to traffic

fixed but hpfm
took me a while to get back to this but today I had bandwidth
strace gave no clues, on a hunch I changed all of the repo entries from http to https and it started working. Weird because curl and wget had no issue with http but yum would time out.
Don't understand it but it works so on to the next issue. "Science is the belief in the ignorance of the experts" – Richard Feynman
