tomcat failing to start after installation (OSS - RHEL 4.5.6_GA_1044)

[davidh]

Hello,

I am trying to install Zimbra on a second machine so I can test backups of the primary instance in order to upgrade it. However, when I install it, I can't get tomcat to start successfully.

The catalina.out file contains:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

There are comments in the forums about the redo.log file needing to be owned by zimbra and not root, but there is nothing in the redolog directory at all. The directory is owned by Zimbra however.

The machine is pretty beefy - 4 Gig of RAM running RHEL-4.

The memory configuration for tomcat is as follows:
[zimbra@localhost ~]$ zmlocalconfig | grep mem
mysql_memory_percent = 50
tomcat_java_heap_memory_percent = 50

I did see a recommendation that mysql needed to be under 2 Gig, so I tried tuning the mysql_memory_percent parameter down to 30%, but that didn't help either.

Does anyone have any suggestions as to what I can look at next?

Cheers,
David

you don't have anything else running locking resident memory do you?

try reducing the java heap ratio and starting.

I can't see anything running of note, although there does appear to be less free memory than expected. However there is still 1.5Gig free.

I tried reducing the memory percentage for java, but that made things worse - zmcontrol status couldn't determine the process status when I did that.

Cheers,
David

OK, I ramped the memory percentages right down to 20% for MySQL and 15% for Tomcat and that appears to have fixed the problem. Must have been a general overallocation of memory for some reason.

Thanks for the suggestions.

Cheers,
David

Our zimbra is installed on a RHEL4 512M ram machine but we cannot get the Tomcat running. Having tried to adjust the % of mysql_memory_percent & tomcat_java_heap_memory_percent to different values, such as 30/40, 20/30, 20/15, 15/10 but none of them works.

Please advice!

Please advice!

Install more memory on your system, that's below the recommended specifications. You could take some steps to reduce the requirements of Zimbra, search the forums and wiki for details.
