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.

Post #424,911 by crazy 7/28/18 9:48:11 PM 7/28/18 9:48:11 PM Reply	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.
