Summary: java.lang.OutOfMemoryError: Java heap space
Key: THRIFT-2284
URL: https://issues.apache.org/jira/browse/THRIFT-2284
Project: Thrift
Issue Type: Bug
Components: Java - Library
Affects Versions: 0.7
Environment: Thrift Server start up by Resin Server at Linux system.
Reporter: hiyoucai
Priority: Critical
Fix For: 0.9.1
【1】The first version application Environment:
# cat /proc/version
Linux version 3.5.0-23-generic (buildd@komainu) (gcc version 4.6.3
(Ubuntu/Linaro 4.6.3-1ubuntu5) ) #35~precise1-Ubuntu SMP Fri Jan 25 17:13:26

# java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
#thrift version is 0.7
Java Server code like following:
public void start() {
try {
logger.info("TNonblockingServer start ....");
TProcessor tprocessor = new
IconOpenService.Processor<IconOpenService.Iface>(iconOpenServiceImpl);
TNonblockingServerSocket tnbSocketTransport = new
TNonblockingServerSocket(19875);
TNonblockingServer.Args tnbArgs = new
TNonblockingServer.Args(tnbSocketTransport);
tnbArgs.processor(tprocessor);
tnbArgs.transportFactory(new
TFramedTransport.Factory());
tnbArgs.protocolFactory(new TBinaryProtocol.Factory());
TServer server = new TNonblockingServer(tnbArgs);
logger.info("TNonblockingServer start OK1....");
server.serve();
logger.info("TNonblockingServer start OK2....");
} catch (Exception e) {
logger.info("TNonblockingServer start ERROR!!!");
e.printStackTrace();
}
}
Problem description:
the thrift server interface invoked per day is much higher.as following:
# wc -l thrift.log.20131209
55598276 thrift.log
In general, the thrift server will be creshed down about 16pm.
I much restart thrift server again an d again,
it is very terrible,My boss will kill me(oh.oh).
I have monitor the JVM,Some information as following:
linux top command result is that the RES item is 9.2G
Why use so many memory?so crazy.
So I use Jmap command print the jvm info that as following:
