Subject AssertionError: attempted to delete non-existing file CommitLog-1292324828581.log
Date Wed, 15 Dec 2010 00:31:15 GMT
Has anyone seen this assert failure below? Seems like a race to delete a commit 
log file. I am running 0.7-beta1, I was wondering if this has already been 
fixed, in which case I can merge that fix in my current tree.
