Summary0002707: symmetric-ds high cpu usage
Descriptionrouter reader threads consume high CPU:
after starting to read a transaction's data from the DB in the fillPeekAheadQueue method, the 'reading' boolean is set to false, which prevents this method from ever completing to read the latest transaction's data, causing the calling loop of execute (while (dataCount < maxDataToRoute || (lastTransactionId != null && transactional)) to call this method for ever.
On our heap-dump we have seen this method has been called for about 61 billion times per thread.
TagsNo tags attached.

What version of SymmetricDS are you using? Can you give us some idea about your configuration and the data that is pending in sym_data?
