Fine tunning on 2 GB RAM with no swap
I have just migrated an installation from: zcs-6.0.4_GA_2038.DEBIAN5.20091214191015
to: zcs-6.0.4_GA_2038.DEBIAN5_64.20091214195434
.
Everything is ok except from receiving external emails.
Once I start the services I can receive external emails for about 5 minutes or so and then it stops receiving external emails and so when you sent an email to my zimbra accounts you get a 554 error.
I already had this problem in the previous installation and I thought that the solution for this was to uncheck TLS autenthication in MTA tab in general setup.
But it seems it is not.
Currently I am using this special setup:
in order not to have RAM problems.Code:zmlocalconfig -e zmmtaconfig_interval=3600 zmlocalconfig -e zmstat_interval=15000 zmlocalconfig -e mailboxd_java_heap_memory_percent=10 zmlocalconfig -e mailboxd_java_heap_new_size_percent=10 zmlocalconfig -e mailboxd_java_options="-server -Djava.awt.headless=true -XX:+UseConcMarkSweepGC -XX:NewRatio=2 -XX:PermSize=128m \ -XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=1" zmlocalconfig -e ldap_common_threads=8 zmlocalconfig -e ldap_common_toolthreads=4 zmlocalconfig -e ldap_db_cachesize=5000 zmlocalconfig -e ldap_db_idlcachesize=5000 zmlocalconfig -e ldap_db_dncachesize=0 zmprov mcf zimbraMessageCacheSize 5000
I have also disabled antivirus and antispam services.
Currently there is about 800 MB free RAM out of 2 GB RAM.
I suppose that the problem comes from the java heap. I suppose that there some java heap settings for some of the zimbra services (apart from the mailboxd setting) but, somehow, it is not documented where they can be changed.
Here there is my zmdumpenv output (11.22.33.44 is not my ip, domain.com is the domain where the machine is, and zimbra.cumulus.lan is a fake domain that it is resolved by a dns server (bind) which lives in the same machine.
I wanted to know what's the difference between mailboxd_java_heap_memory_percent and mailboxd_java_heap_new_size_percent?Code:---------------- 20100328001357 ---------------- uid=1002(zimbra)

Because sometimes with 600 MB RAM I have seen some messages in random services that say that they could not create the java virtual machine because there was not enough memory and it does not make with 600 MB RAM free.
Any help is welcome and do not hesitate to ask me to run more commands in order to find my problem.
