Re: Jenkins on Websphere 8.5 - out of memory (heap)

2016-09-21 Thread Tomáš Mrázek 
300kb is not much, but if you look at the implementation of the called 
method 
https://github.com/kohsuke/winp/blob/master/src/main/java/org/jvnet/winp/WinProcess.java
 
,I got heap exception at line 144. The method creates substrings in loop 
string lenght > 0. So theoretically after each iteration it stores to RAM 
another string with one character less.

Re: Jenkins on Websphere 8.5 - out of memory (heap)

2016-09-20 Thread Baptiste Mathus 
I must be missing something. 15 characters is not that much in memory.
Let's say around 300 kilo bytes actually in the JVM memory in utf 16. So I
don't get where those 11GB come from.

Or do you mean 15 strings of characters of various sizes?

Cheers

JDK1.8, max heap was set up to 2048M. Implementation for 
that WinProcess.parseCmdLineAndEnvVars is by creating substrings with one 
character less and with my baisc calculations, with 150k char String and 
possibly zero GC I would need 11 gb, That's out of question for such a 
simple task.There must be something wrong between native method ang getting 
env variables from WAS.

Jenkins on Websphere 8.5 - out of memory (heap)

2016-09-19 Thread Tomáš Mrázek 
So I installed 2.7.4 on Websphere 8.5.5.9.

I'm running job with a maven build. Everything is fine, ear is created, but 
after that Jenkins stucks and throws Heap error (while creating enviroment 
variables like JENKINS_HOME).

FATAL: ...java.lang.OutOfMemoryError

So I tried to run simple Groovy script in Jenkins console 


import org.jvnet.winp.Native;
println(Native.parseCmdLineAndEnvVars("jenkins server pid"))


and I got string with 150k chars long, where only first thousand are regular 
chars with env variables and the rest is some chinese weirdo chars. I tried to 
run Jenkins with UTF-8 by specifying

-Dclient.encoding.override=UTF-8 which ofc does not help. 


I'm quite hopeless and I don't know, how to fix this. Any suggestions?
