Re: [Condor-users] Vanilla job crashing segmentation fault due toioctl [Sec=Unclassified]

["Troy Robertson" <Troy.Robertson@xxxxxxxxxx>]

Yes, I should probably have shown the line before that in the strace:

readlink("/proc/self/fd/0", "/dev/null", 511) = 9
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe20890) = -1 ENOTTY
(Inappropriate ioctl for device)

I am told that apparently the program makes a getlogin() call which
returns the username of the login associated with the 'controlling
terminal'.  The problem can be duplicated by running the program
directly with < /dev/null piped to it.  I have tried putting a username
into an input file to no avail. 

Submit file is as follows:
Universe = Vanilla
Requirements = Arch == "INTEL" && OpSys == "LINUX"
Executable = CASAL_LINUX.exe
Arguments = -e -O mpd.dat

#Input = LINUX_input.txt
Output = LINUX_output.txt
Error = LINUX_error.txt
Log = LINUX_log.txt

transfer_input_files = estimation.csl, population.csl,  output.csl,
mpd.dat
should_transfer_files = ALWAYS
when_to_transfer_output = ON_EXIT
getenv = TRUE

Queue


Thanks guys

Hi,

It is stdin that is missing (see the 0 for file
descriptor). You get ENOTTY as the job is not
connected to the terminal.

Maybe post the job submit script?
