memory probelam

Postby MAORSH » Mon Sep 17, 2018 3:24 pm

hello I have
windows 7 64 bit with 8 gb memory
I have java 1.6 as 32 bit apps (we have a lot off dll that 32 bit
my problem
I run my apps with
-xms=500m -xmx=500
the apps run with 250mega the task manager show 400 mega
I try yourkit and I do not found the problem
the heap use is 250m the permsize is 65m
so how the task manager show 450m
in the time that I work with the apps the heap size +perm size get together to 400m
but in the task manager the commit memory of java 1.4g
and then the jvm is cursh
how did I can fix or found what my probelam

The JVM uses memory outside the heap and non-heap memory pools:
https://www.yourkit.com/docs/kb/sizes.jsp
In particular, the 32-bit dlls you mentioned likely allocate native memory.

To provide detailed analysis, we need:
- the crash detail: the crash log file hs_err<pid>.log
- the profiler agent log file <user home>/.yjp/log/<session name>-<pid>.log

Please send them to support@yourkit.com if you cannot share them in the public forum.

thank you
but i do not know how to get the files ?
if when i run the apps on begin i want to create you the detailed analysis,
to understand where is 200m
and then
after i work with my app
every one action the task manager grow with 50m
until he get to 1.5g and then the jvm crash
To provide detailed analysis, we need:
- the crash detail: the crash log file hs_err<pid>.log
- the profiler agent log file <user home>/.yjp/log/<session name>-<pid>.log


* thank a lot
