mktemp: failed to create file via template

Hi, I'm seeing this in some job (pair) log files (e.g., https://www.starexec.org/starexec/secure/details/pair.jsp?id=43489107 ) while other pairs from the same job ( https://www.starexec.org/starexec/secure/details/job.jsp?id=6592 ) went fine.

mktemp: failed to create file via template `/tmp/1561177.1.all2.q/tmp.XXXXXXXXXX': No such file or directory

Thanks for reporting this. I have to imagine this is a transient system error, as it is reporting a problem running the mktemp command. The lines from our script that are triggering the error are:

TMP=`mktemp`

echo $SOLVER_NAME > $TMP

Not much room for a bug in our code there, although it looks like maybe somehow the TMPDIR environment variable is getting set (we are not setting it in our code), since the temporary file in question is "/tmp/1561177.1.all2.q/tmp.XXXXXXXXXX". I'll change our script so we specify /tmp explicitly to mktemp.

Thanks,
Aaron
