I run this on a 16-core AMD Windows Server 2008 R2 machine. In about 1 out of 10 times, I get a "git fetch origin" that uses 100% of a core until killed. It just happened again a few minutes ago: $ ps aux PID PPID PGID WINPID TTY UID STIME COMMAND 2720 1 2720 2720 ? 11003 09:56:55 /usr/bin/bash 4704 1 4704 4704 ? 11003 10:12:15 /usr/bin/mintty 2712 4704 2712 3108 pty0 11003 10:12:15 /usr/bin/bash 5344 5248 5248 2508 ? 11003 10:07:37 /usr/bin/bash 3116 1 3116 3116 ? 11003 09:56:54 /usr/bin/bash 5432 1312 5248 6004 ? 11003 10:07:40 /usr/bin/ssh 2028 2712 2028 3220 pty0 11003 10:18:48 /usr/bin/ps 4692 3688 4692 3600 ? 11003 09:56:21 /usr/bin/rsync 3688 1 3688 3688 ? 11003 09:56:21 /usr/bin/cygrunsrv 2468 1312 5248 4844 ? 11003 10:07:42 /usr/lib/git-core/git 1312 5344 5248 1196 ? 11003 10:07:39 /usr/bin/git 5248 1 5248 5248 ? 11003 10:07:37 /usr/bin/bash 1580 1 1580 1580 ? 11003 09:56:57 /usr/bin/bash 1412 1 1412 1412 ? 11003 09:56:56 /usr/bin/bash I tried strace, but it got a "Segmentation fault" on both the above git processes. What can I do to debug this?
