Re: [ZODB-Dev] Weird ConflictErrors with Zope 2.8.4 - It's been a while ; -)

Rather than chucking this in the collector as-is, it would be useful if you could get me the output of the ZEO log rather than the output of the client log. Right now, the actual traceback is in the ZEO log; the client log only shows that a conflict error happened; not where it happened.

[ZODB-Dev] Debugging ReadConflictErrors on ZODB 3.4 (Zope 2.8)
