[Swift-devel] Could not convert value to boolean

[Ketan Maheshwari]

Hello,

Today, I saw this error in a simple catsn script running from engage submit
host to OSG via GWMS.

The run involved 98 tasks out of which 2 failed with the error message:

This does not happen in each run. Out of 4 such runs that I tried, it
happened in one run.

The complete log is here:
http://www.mcs.anl.gov/~ketan/catsn-20111202-1627-0e9196p8.log

In the log, I see a couple of "Broken pipe" messages but am not sure if the
two are related in any ways.

I had 50 workers running.

The coaster service log is:  http://www.mcs.anl.gov/~ketan/swift.log
