JRE:
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01)
Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode)
JVM Args:
-Xms128m -Xmx128m -XX:MaxPermSize=64m
Problem when the java process runing after a while,resident memory has an increase of 200M.
/proc/${PID}/fd and jstack have no changes.
Then I use gperftools to analyse the memory,as fellow:
time1:
124.5 31.5% 80.0% 124.5 31.5% pthread_create@@GLIBC_2.2.5
time2:
162.6 37.3% 81.2% 162.6 37.3% pthread_create@@GLIBC_2.2.5
'pthread_create@@GLIBC_2.2.5' calling increase from 124.5M to 162.6M
pthread_create 中是否存在 JRE 1.6 内存泄漏?
