JVM crashes on startup. (Error 8 allocating x Bytes)

[Former Member]

Hello,

I recently installed Netweaver 2004s SR2 Developer Workplace in my Windows XP development machine (Core 2 Duo 2,33Ghz and 2GB of RAM).

The problem is that I haven't been able to start the J2EE engine. I checked the "Developer Trace" (on SAP MMC) and apparently it was an issue with some misplaced dlls (see notes: 943602, 940893, 736462, 856393, 129813 and 664269) which could be corrected by setting some environment variables in order to tell jlaunch to preload the conflicting dlls.

However, after a more detailed analysis of the logs I found that there was another error. Here is the relevant excerpt from std_server0.out:

--------------------------------------------------------------------------------
stdout/stderr redirect
--------------------------------------------------------------------------------
node name   : server0
pid         : 2716
system name : DW0
system nr.  : 00
started at  : Tue Apr 10 15:33:32 2007

Error 8 allocating 0x70000000 Bytes at 0x0

Then there is the address space layout for jlaunch and then the final part of the message:

------------------------------------------------
Address                   : 0.005 sec
Elapsed Time              : 0.010 sec

------------------------------------------------

[Thr 3904] MtxInit: -2 0 0
Error occurred during initialization of VM

Does anybody know what does that Error 8 mean and how can I solve it? Thanks in advance for any help.

Hi Salvador,

Please upgrade your jdk and jre.

I have also installed the same package recently.

The version of jdk, ,jce and jre is 1.4.2_13.

If you have this or higher, then there problem can be somewhere else.

Check out the SAP notes.

Hi Prashil, thank you very much for your suggestion. However, I'm almost certain that I'm trying to run the engine with jdk 1.4.2_13. I'll try uninstalling all other versions of the jdk (as I have 1.5 and 1.6 also installed) and I'll let you know how it went.

Also, do you know what does that Error 8 mean or where could I find such information?

Regards,

Salvador

Hi Salvador,

No i don't have much idea regarding the error. But the SAP notes that were suggested (943602, 940893, 736462, 856393, 129813 and 664269) is all related to JDK and JRE version.

Thats why i am pretty sure that your the issue is with java versioning only.

I would suggest uninstall all JDK and JRE on the system and configure only for JDK 1.4.2_13.

Please also take care that the JAVA_HOME and classpath is properly configured.

Award points if you feel the solution is helpful!!!!

Thanks,

Prashil

Well, I uninstalled all other jdk and jre in my machine but still no luck.

JAVA_HOME and PATH are also correctly set (although there is another env. variable called "Path", could this one conflict with PATH?).

I also tried adding environment variables for preloading dlls but when the memory reservation fails, the preloading doesn't take place.At this point I'm pretty sure it's a memory allocation issue but I just don't know how to solve it, is there any way to limit the maximum memory allocation for an application? Is there a setting I can change in windows?

Sorry for not rewarding points yet, but I don't feel the answers were helpful.

Regards,

Salvador

Hi Salvador,

You can try to increase the virtual memory. Its in context menu of the "My computer--> Advanced" tab in the Setting for the Performance Advance table change the virtual memory allocation.

Hope this helps!!!

[Former Member · Accepted solution]

Well, that's one of the first things I tried, it is set to the maximum (4G) so I can't increase it anymore.

Now, just to make sure, am I supposed to have 2 instances of jlaunch running after trying to lauch the j2ee engine?

And could you tell me what I should see in the std_server0.out ? (or what do you have in it)

The part that intrigues me the most is this one:

-

---

Virtual free : 2020660 K

Virtual commit : 27316 K

<b>Virtual reserve : 48988 K</b>

-

---

So, does that mean that it reserved only 48988K of virtual memory? Even though there are almost 2G of free virtual memory ?

[prashil · Accepted solution]

No i have only 1 instance of jlanch.

I am posting what i have in my std_server0.out

I managed to get rid of the memory allocation error by entering a lower value for the environment variable jlaunch/ReserveSize (It doesn't work for 0x60000000 but it does for 0x40000000).

Unfortunately there were still dlls fragmenting my address space, so I tried to restore my computer to a previous state and now I can't boot Windows.

I'll have to try an installation repair and if that doesn't work I'll have to reinstall the whole system.

[Former Member]

So, to summarize:

Error 8 allocating x Bytes at 0x0000 

means that jlaunch is trying to reserve too much memory. Try creating environment variable jlaunch/ReserveSize and setting it's value to something lower. Once the memory allocation is reported as sucessful in std_server0.out you can start tackling the memory fragmentation (preloading dlls with jlaunch/PreloadDLLs environment variable)

Thanks for the solution!!!!!

That will help if anybody stuck with same kind of solution

Best Regards,

Prashil
