OFBiz crash on high load
Locked
 
|
Dear all
I'm using OFBiz in a large company, and the users are more than 400. The ofbiz is running on win2000 server as OS and on hp proliant server 3GB Dual Processor and 3GB RAM, and the DB is on another sever. The run command is: "%JAVA_HOME%\bin\java" -Xms256M -Xmx1024M -jar ofbiz.jar In the rush-our the system Hang up and does not accept any request, so I shut down the ofbiz and restart it again. And when I request a page which retrieves more than 5000 records I get a white page in the explorer. I have made some configuration on ofbiz-containers for ajp, http, https like this <property name="debug" value="0"/> <property name="enable-lookups" value="false"/> <property name="enable-keep-alive" value="true"/> <property name="compression" value="on"/> <property name="allow-trace" value="false"/> <property name="min-processors" value="15"/> <property name="max-processors" value="300"/> <property name="max-keep-alive" value="-1"/> <property name="max-header-size" value="4096"/> <property name="max-post-size" value="8097152"/> <!-- 2mb --> <property name="buffer-size" value="4096"/> <property name="accept-count" value="300"/> <property name="connection-linger" value="-1"/> <property name="connection-timeout" value="2400000"/> <property name="upload-timeout" value="600000"/> <property name="socket-timeout" value="0"/> but the problem is still exist, and I'm taking an exception like this: ---- exception report ----------------------------------------------------------

BTW I have read recently that on Windows you can't get more than approximatly 1.5GB of Heap See here for instance : http://www.velocityreviews.com/forums/t144234-help-ltgc-reduced-max-java-heap-size-to-bytes-due-to-memory-contraintsgt-.html The explanation come from the implementation of the garbage collector : it needs an continuous segment of memory.

In reply to this post by Mamdouh Kaadan-2
That's true Jacques, I tried to make it more than 1024 but the ofbiz does not start at all, and I can't move to UNIX or Linux before one month at least.
My version of ofbiz is from more than one year, and if i want to make upgrade now to the last version, I think it needs long time, but I want to upgrade to the last version ASAP. HyperThreading in the BIOS is turned on. My SDK version is 1.4.2_05 What are the services that can I turn off? There is no problem with the services or with the antivirus, I think the problem is that there is some problem in JOTM in my version maybe, because the following warning appears all the time: ----

not sure this has an effect
have seen different threads about 1.4.2 having problems. _11 is the latest.

What's your commit charge look like under load? Have you turned all the other services off that are not related to your OFBiz installation? Will TPTB at your enterprise allow you to run the OFBiz server using a "normal" ServerOS like Linux,Solaris,FreeBSD,Mac-Xserve? When did you last do a SVN update with OFBiz? Do you have some anti-virus running? Have you tried setting the Processor affinity to a single CPU? Did you turn off HyperThreading in the BIOS? |

With my minumal control of the American English language, I should never try to act like I really know how to invoke Latin phrases. As demonstrated, I have no clue when to invoke them singularly and properly. -- Walter |
