After upgrading to Hudson 1.379 and ClearCase 1.3.1, our polling is no longer working. We have an environment variable in our view names (to shorten our often-verbose computernames). For some of the polling commands, the resolution is working fine. You can see that in the command output the SHORT_COMPUTERNAME variable has been resolved properly form the lsview command.

Done. Took 1 sec
No changes

But we're seeing this in our hudson.err.log at each polling interval:
