I have a Mac mini (Late 2012), 2.3 GHz Intel Core i7 Processor, 4 GB 1600 MHz DDR3 Memory that runs OS X Server 5.1.7.
Three times recently (I think since the upgrade to Server 5.1.7), the machine has become completely unresponsive and I have had to reboot it. On both occasions the fan was blowing full blast.
Given the complete lack of response I get the impression the CPU is completely tied up, but I can't see what process/es is/are causing it.
After the second occurrence I poked around in the log files a bit. In
system.log I found the following, which had been repeating for hours:
Aug 4 10:06:11 s-mx-01 configd: could not allocate mach port: (os/kern) no space available
I went back and tried to find out when it had started and found this:
Aug 3 18:05:44 s-mx-01 configd: BUG in libdispatch: 15G31 - 384 - 0x1000600c Aug 3 18:05:44 s-mx-01 configd: could not allocate mach port: (os/kern) no space available
Does anyone have any idea what this might mean? And how to fix it?
