------------------------------------
Summary: Tcp mem and socket domain socket leak in flume 1.7 and
earlier versions.
Key: FLUME-3257
URL: https://issues.apache.org/jira/browse/FLUME-3257
Project: Flume
Issue Type: Bug
Affects Versions: 1.7.0
Reporter: zhenzhao wang
Fix For: 1.8.0
We'd like to report a resource(tcp mem, domain socket) leak caused by
THRIFT-2402 . The problem is solved in 1.8.0 as it upgraded libthrift to 0.9.3,
however we think it's still useful to share our experience with flume users.
The sources which use libthrift server might encounter the resource leak
problem, e.g. ScribeSource. The bug could be very serious (leading node
unreachable in our case) while satisfying following conditions:
# Flume stop and start thrift server (e.g. scribe source) in the same process
due to configuration reload and etc. Every stop and start action will cause
resource leak.
# The server's traffic is very high. The leak might be quite big when the
traffic is high.
