Red Hat Bugzilla – Bug 487966
Application bug, race in MSG_PEEK
Last modified: 2009-05-11 06:08:24 EDT
Description of problem:
Found this in kernel logs, no additional info available
kernel: TCP(fetchmail:12072): Application bug, race in MSG_PEEK.
(greping logs for MSG_PEEK reveals lots of older occurrences I didn't notice before)
Thanks for report. The log message is present in fetchmail for longer time (I think since Fedora 8). Upstream is aware of this issue and working on fix.
Here you can find additional information:
"That's in fact a bug in Linux kernels around the late 2.6.2X versions, rather than fetchmail. Fetchmail has no race bugs around MSG_PEEK, as of version 6.3.9. The message can safely be ignored."
