Hi,

Any ideas on how to rectify this error? The following stack trace appears towards the end of the build and I am using 1.310

Re: ERROR: Asynchronous execution failure

It appears that you had a file corruption. You can just delete
d:\work\software\data\hudson\fingerprints\56\28\65ae650a067a0c92aa2fca26dd73.xml
 to recover.

I've thought about letting Hudson silently do this, but it was difficult
for Hudson to see if the problem is caused by a corrupt file or by some
other transient problems (in which case deleting a file would be too
much.) Therefore, for now we have to ask humans to do it.

Re: ERROR: Asynchronous execution failure

Yes, I happened to remove this xml file couple of days ago and I don't see this error again.
