Hi,

I've encountered a weird problem today.

The thing is that I configured a job to poll on git SCM every 5 minutes.  But the Polling never happen.

When I look at the Polling Log, it said "polling has not run yet".

I bounced the server and the polling start to work.

However, it only run once after the re-bounce.

After some debugging I found that the "Hudson cron thread 1" thread throw an exception with thread being blocks.

Below is a stack trace on the "Hudson cron thread".

Apparently, this was due to one of a newer version of URL Change plugin, version 1.4-h-2.

I disabled this URL Change plugin version and things work like a charm.

However, filing this bug after a discussion with Winston.  Per Winston, Cron thread should be recoverable if a particular poll fails.

Thanks,

David
