[Swift-devel] SGE's qstat output parsing failure

[David Kelly]

Thanks Luiz. I've seen some similar issues with 0.92 when parsing qstat output. qstat output tends to change between versions which can cause parsing problems like this. For 0.93, we will be using the XML output to help standardize things a bit.

Regards,
David
