King, III changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jim.king at simplivity dot com --- Comment #20 from James E. King, III --- I can also confirm that we were able to reproduce this issue easily and once the patch was applied, we were not able to reproduce it easily any more. It can show up in a core looking like https://sourceware.org/bugzilla/show_bug.cgi?id=12926 with a hang in check_pf holding a lock, and all other threads calling getaddrinfo() are blocked waiting for a reply that may never happen. -- You are receiving this mail because: You are on the CC list for the bug.
