Package: nagios2
Version: 2.0-1
Severity: normal
Tags: patch
Using debian unstable's nagios2 on a 64-bit system, I get this at start-up:
[1142950705] LOG VERSION: 2.0
[1142950705] Warning: Size of service_message struct (528 bytes) is >
POSIX-guaranteed atomic write size (512 bytes). Service checks results may get
lost or mangled!
[1142950705] Finished daemonizing... (New PID=18989)
Here's a patch that solves the problem for upstream's
nagios-2-x-bugfixes branch:
* include/objects.h [MAX_PLUGINOUTPUT_LENGTH]: Decrease length
by 16, so that `sizeof service_message' is no larger than 512,
even on x86_64 systems.

FYI, I tried to report it upstream, but was unable to
