[SOLVED] Memory Upgrade --> MTA Error

[carlitross]

Hi guys.
Let me congratulate you for the excellent job developing Zimbra.... It's amazing.

I implemented ZCS5.02 in a Dell Pwer Edge SC1435, with one AMD Opteron proccessor, and 4 GB Dual Ranked RAM. It has 1 TB of HDD.

It' works great for the first 400's users in two domains, but when i imported 700 users more to one adittional new big domain in the same server, the spamassasin consumed all the ram. Solution: We bought 4 GB adittional, dual ranked with the same model that the "old Ram".

When i started again the server, after the memory installation, I saw that the memories were recognized by the BIOS and th OS. Zimbra starts but it's send me this error message:

antispam Running
antivirus Running
ldap Running
logger Running
mailbox Stopped
zmmailboxdctl is not running
mta Running
snmp Running
spell Running
stats Running

I read a lot of threads (trust me a lot of threads, like 230), and i worked a lot that night trying all the possible solutions, but i cannot solve the trouble. When i take out the new memories from the server, it starts normally; but i have to disable the antivirus and spam filter.

I have 2 questions:
1st: What i have to do to Zimbra recognizes the new memories in a "clear way"?
2nd: Is needed re compile the kernel and reinstall zimbra again?

The OS is Centos 5 and the distro of zimbra is:
5.0.5_GA_2201.RHEL5_20080417012110 CentOS5 FOSS edition

While i have unprotected my server What kind of anti spam do you recomend me to put like a proxy front end?
Thans a lot.

Best regards...

Thanks uxboxd for you fast reply.

I was looking inside of the /var/log/maiilog & /var/log/zimbra.log files, and their older versions, but just show me the postfix logs of the last days. (The memory trouble happened 4 weeks ago).

Where i can find the logs of that date?
thanks again

They will have been tar'd up in /var/log eg. zimbra.log.1.gz

I untar'd all the zimbra.log.*.gz, but all files inside only have the logs of the last days.

Is there another place where find the logs?
About the question, have you read before a hardware problem like this one?

Maybe today at night (i'm in -4:00 GMT time), i can put the memories again and i'll get all logs of the maillog...
Must i search in another file than maillog? Where do you suggest me to search?

Thnx a lot!

run these two commands to see what percent of memory is allocated to jetty & mysql:

zmlocalconfig mailboxd_java_heap_memory_percent
zmlocalconfig mysql_memory_percent

32-bit systems frown on installs with >4GB of ram. if you have 8GB of ram, you may need to manually downsize your *_memory_percent config to no more than 25 percent (or 2GB).

Hi danielfarrelly...

Thanx for you reply.
look, this is the result of the percent of memory allocated to Jetty & MySQL:

[zimbra@mail bin]$ zmlocalconfig mailboxd_java_heap_memory_percent
mailboxd_java_heap_memory_percent = 37
[zimbra@mail bin]$ zmlocalconfig mysql_memory_percent
mysql_memory_percent = 50

As you said, are over that 25 percent.
How i can downsize them??

Thanks a lot... more than 2000 users will be eternally in debt with you.

Danielfarrelly: If i see you sometime in this life, please remember me this day, and let me to invite you a couple of beers...

It's solved.
I just executed as zimbra user:

zmlocalconfig -e mailboxd_java_heap_memory_percent 25
zmlocalconfig -e mysql_memory_percent 25

And the problem go off!
Thanks you very much!!!. I never have been solved it without your help.

I Hope that this thread can helps someone.
Good luck.
