35751 71 d 2 h amit /trunk/PyProj/src/shop2020/model/v1/order/impl/ TransactionServer: add session.expunge_all() and periodic gc.collect() in close_session() to prevent memory growth from ORM identity map accumulation and Python 2.7 memory fragmentation  
35734 72 d 1 h amit /trunk/PyProj/src/shop2020/model/v1/order/impl/ Remove AlertClient dependency from order DataAccessors and ObsoleteDataAccessors  
35718 73 d 16 h amit /trunk/PyProj/src/shop2020/ fix: use session.remove() instead of session.close() to prevent memory leaks in all services  
35701 73 d 23 h amit /trunk/PyProj/src/ Performance fix: reduce logging level to WARNING, remove incompatible pool_pre_ping, fix tornado dependency

- Changed logging.basicConfig from DEBUG to WARNING in 6 service files to stop
SQLAlchemy query spam that caused memory bloat (TransactionServer 553MB -> 63MB)
- Set echoOn=False as default in PurchaseServiceHandler
- Removed pool_pre_ping=True from 7 DataService files (incompatible with SQLAlchemy 0.6.6)
- Updated tornado dependency from 1.0.1 to 1.0 in setup.py (1.0.1 unavailable on PyPI)		  
35608 85 d 23 h amit /trunk/PyProj/src/shop2020/ Fix DB connection pooling to reduce service restarts

- Add pool_timeout=30 to fail fast instead of hanging indefinitely
- Add pool_pre_ping=True to detect stale MySQL connections before use
- Reduce pool_recycle from 7200s to 3600s for fresher connections
- Disable SQL echo logging (echo=False) to reduce memory/CPU usage
- Fix MongoDB connection with thread-safe initialization and proper pooling
