Database errors cause all worker threads (and the corresponding stuffer thread)
to wait indefinitely
----------------------------------------------------------------------------------------------------
Key: CONNECTORS-220
URL: https://issues.apache.org/jira/browse/CONNECTORS-220
Project: ManifoldCF
Issue Type: Bug
Components: Framework crawler agent
Affects Versions: ManifoldCF 0.2, ManifoldCF 0.1, ManifoldCF 0.3
Reporter: Karl Wright
Priority: Minor
When ManifoldCF gets a database error from a thread, it tries to recover by
resetting all threads to a known state. Unfortunately this code seems to fail,
and you wind up with a frozen crawl with all worker threads in the following
state:
"Worker thread '36'" daemon prio=6 tid=0x00000000077ed000 nid=0xa98 in
Object.wait() [0x000000000b1af000]
java.lang.Thread.State: WAITING (on object monitor)
