Bug #8541
Updated by Peter Amstutz over 8 years ago
According to the discussion at http://cosmicpercolator.com/2016/01/13/exception-leaks-in-python-2-and-3/ exceptions can keep stack frames live far past when they are no longer needed, which may be the cause of our memory leaks.
Audit exception handling in node manager and use sys.exc_clear() discard exception tracebacks where possible.
