JAVA Server process are down

[Former Member]

Hi all,

I am newbie in SAP Netweaver AS JAVA administration.

In one of JAVA system (wtih no ABAP stack), 4 Server process (out of 2 Server Process) were down all of sudden.

When checked, the logs were showing the below error:

Option is not recommended for use in environments: -XX:+HandlePromotionFailure

Option is not recommended for use in environments: -XX:-UseNewHashFunction

[Thr 4] Mon Feb 6 11:09:13 2012

[Thr 4] JHVM_LoadJavaVM: Java VM created OK.

: [50] 11:09:13 ***ERROR (error_messages.c:67): ERROR: transport error 202: UNKNOWN

: [50] 11:09:13 ***ERROR (transport.c:580): JDWP exit error

We have tried to restart the Sever process via jcmon but nothing worked.

Can you please help?

with regards,

Raja

Raja,

Go to the ConfigTool and open the NODE which are down and remove the below parameters - Save it and restart the Server node. You should be good.

-XX:+HandlePromotionFailure

-XX:-UseNewHashFunction

Hi Arjun,

The restart of Server node after the removal of the below parameters didn't work.

-XX:+HandlePromotionFailure

-XX:-UseNewHashFunction

Now, I see the Server Nodes 0 and Server Node 3 ( out of 6 Server Nodes) are only running.

Rest of the Server Nodes were waiting to restart initially but ultimately they all stopped.

Previously it was Server Node 0 and Server Node 1 which were running and rest of the nodes were down.

Kinldy suggest.

with regards,

Hi,

Please monitor the states of JAVA server process carefully when restarting.

If bootstrap and sync with DB is done and server is failing in starting framework then check the work dir .boo , .out files,dev_jcontrol and dev_server 0 process log files.

Check whetner all of them any same memory settings .

check the Java VM properties for all the server nodes .

Can you please provide the logs of std_server files . These files will show the errors.

Hello,

Problem is you are using 4 server nodes with less available memory on the server.

You can check your VM and heap parameters in Config tool. If you are good with the parameters then there are chances of memory bottle neck on the hardware side.

Hi,

Regarding this check the note Note 723909 - Java VM settings for J2EE 6.40 7.0 to see JVM parameters.
