Hello, I am trying to run fio on windows (2012 core), and getting sporadic crashes (~ 1 out of 3 runs) - Tried both 2.13 (taken from bluestop site: fio-2.13-x64.zip) And also compiled 2.14 from sources. In both binaries, when I run the following command: fio.exe --thread --direct=1 --output-format=json --output=\fio.results.192.168.1.53.json --name=writeTestFile --filename=E\:\throughput.tst --size=100m --rw=write --bs=256k --iodepth=2 --buffer_comp ress_percentage=0 The test completes (gets to 100%) and then crash: Faulting application name: fio.exe, version: 0.0.0.0, time stamp: 0x57bf1de1 Faulting module name: msvcrt.dll, version: 7.0.9600.16384, time stamp: 0x5215f944 Exception code: 0xc0000005 Fault offset: 0x0000000000003209 Faulting process id: 0x914 Faulting application start time: 0x01d218fd8209cc06 Faulting application path: c:\fio\fio-2.13-x64\fio.exe Faulting module path: C:\Windows\system32\msvcrt.dll Report Id: 6ca2ff1e-84f1-11e6-80c4-06db2ed6a2ef Faulting package full name: Faulting package-relative application ID: The output file (--output=\fio.results.192.168.1.53.json) is empty. I was able to narrow the problem to creating json output, e.g., when text output is requested, the crash does not happen. fio.exe --version fio-2.14 Thanks in advance Shahar -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
