--- Comment #6 from Faidon Liambotis <[email protected]> --- Sorry for not updating the ticket earlier -- I've actually attempted to debug this and have chatted with Aaron last week or the one before that. I've verified that at the time errors were spawned, DNS replies were coming into the system. Also, it's peculiar how no other infrastructure seems to be affected, not even the application server ones (this apparently affects only job runners). It's also something that has manifested recently, possibly after the precise upgrade. I have some suspections that it may be curl-related (curl has an internal DNS cache that is enabled by default, so it's not just simple libc resolver calls). I've asked Aaron to isolate the code in question and produce some kind of script that we can run repetively, reproduce and run under strace/gdb, rather than trying to attach them on random jobrunners and hope we catch it. The issue happens on jobrunners, so it's under php cli anyway, so the environment won't be that different anyway. -- You are receiving this mail because: You are the assignee for the bug.
