zimbra open source 5.0.14 and java?

[aurfalien]

Hi all,

I upgraded from 5.0.12 to 5.0.14 and am now seeing that my box takes twice as long to finish booting.

Java now seems to take up 100% of my cpu for 2-3 minutes and then all is well.

What I run;

RHEL 5.3 (2.6.18-128.1.1)
Zimbra open source 5.0.14
Java 1.4.2

Zimbra seems to be working normally but I just find the new behavior odd.

How much memory does your server have ? Could you post the following to help us understand your environment

top
freemem
cat /proc/meminfo

Out of curiosity what do you have running Java 1.4.2?
(ZCS 5.0.14 includes JDK 1.5.0_17-b04)

Thats a good question.

Nothing really, it only appeared after the 5.0.14 install so I assumed that it was part of some Zimbra need.

ps output, filtered for java.

Is that a java installed elsewhere? ZCS uses: /opt/zimbra/ls -la | grep java
(Should point to /opt/zimbra/jdk1.5.0_17)

[aurfalien]

You are right, I just did a java --version as root.

The java that is causing serious cpu usage upon boot is the Zimbra java.

I appended my earlier post with some ps info.

Any updates on this?

Zimbra now takes 3 times as long to start due to Zimbra Java.
