Nagios 4 on Solaris 10

[Ton Voon]

Hi,

I spoke too soon. While we've got it compiling, Nagios 4 still doesn't seem to work correctly. It appears that with the -DIOBROKER_USES_SELECT, the Nagios worker threads go into a loop and don't get any of the responses.

The test-iobroker appears to work okay, but I can't see where to look next. Any Solaris experts want to have a look?
