A network service error has occurred

Hi,

Recently i change the public ip of our mail server (Release 5.0.5_GA_2201.SLES10_64_20080417011732 SLES10_64 FOSS edition). I changed the ip of nameservers that this server uses too.

Some times, when i try to login i got following error :

Quote:

A network service error has occurred.

In the top of the login screen. I did not found any error into the logfiles.
After reboot service with zmcontrol command it worked fine. But the mistake repeats itself from time to time.

I read this thread
http://www.zimbra.com/forums/install...client-io.html

And found this warn/info messages on mailbox.log:
2009-10-08 11:01:19,429 INFO [btpool0-40] [ua=zclient/5.0.5_GA_2201.SLES10_64;oip=80.36.225.46;] SoapEngine - handler exception
2009-10-08 10:24:29,700 WARN [btpool0-59] [] soap - Unable to look up zimbraSoapRequestMaxSize. Not limiting the request size.

Where i can get the correct zimbra.soap.url ??
I should increase the Heap Space?? How i can do this?? Editing zmmailboxdctl??

#
# Memory for use by JVM
#
memkb=$(zmsysmemkb)
jm=`expr $memkb '*' ${mailboxd_java_heap_memory_percent} / 100 / 1024`

PD: I found this with zmlocalconfig command

zimbra_zmprov_default_soap_server = localhost

How i can try to test localhost/service/soap, for example

We have the same error, some hours later. I see this WARN in mailbox.log while the network services crash down:

[hr]

I increase the -Xmx JVM option value on /opt/zimbra/bin/zmmailboxdctl to 4096 MB. The default of mailboxd_java_heap_memory_percen value was 40%. Now is 68'5%. We have 6 GB RAM on our server.

Zimbra recommend against increasing the heap size to more than 30% of system memory.
