LRUMap problem; resetting LRU

[SkipDever]

I am getting this error in the log during a data import with debug=WARN.
Dont recall ever seeing it before.  When this happens, the CPU pegs and no
further imports happen.

Here is the code (from ServiceDispatcher) where the error originates from:

    private RunningService logService(String localName, ModelService
modelService, int mode) {
        // set up the running service log
        RunningService rs = new RunningService(localName, modelService,
mode);
        if (runLog == null) {
            runLog = new LRUMap(lruLogSize);
        }
        try {
            runLog.put(rs, this);
        } catch (Throwable t) {
            Debug.logWarning("LRUMap problem; resetting LRU [" +
runLog.size() + "]", module);
            runLog = new LRUMap(lruLogSize);
            try {
                runLog.put(rs, this);
            } catch (Throwable t2) {
                Debug.logError(t2, "Unable to put() in reset LRU map!",
module);
            }
        }
        return rs;
    }

Anyone have any idea what the source of the problem is.  This happens after
about 4000 records are imported, so adding System.out stuff or stacktraces
would not be possible.
