Server uses all resources when I turn on the POP/IMAP proxy

[mshatski]

Hi,

We have been using Zimbra Open Source for the last 6-7 months, and so far it is way, way better than the previous Exchange server we had.
Everything worked really really great, until we needed to turn the IMAP proxy on, so our SugarCRM installation could download our user's email boxes.
When I turn the proxy on, the Zimbra server starts using all the resources until it reaches 100% (RAM, processors) and it becomes really slow.
I looked in the forums but didn't find anything, any ideas?

By the way, if it helps, it is running in a VM under VmWare ESXi 3.5 U4, 4 GB Ram, 500 GB hard disk, 2 processors assigned.

Thank you!

The proxy is not needed on a single server installation. Which version of ZImbra are you using, please update your forum profile with the output of the following command (don't post it in this thread):

zmcontrol -v

updated, thank you Phoenix!

I'm sorry, I meant that what I described happens when I enable the IMAP service, not the IMAP proxy (Servers\<my server>\IMAP tab) . Sorry about that, it's really early here and i'm sleepy!

There shouldn't be any increase in CPU usage when the IMAP service is enabled, are you saying that you have 4GB of RAM allocated to the Zimbra VM?

Actually, I double checked when I read your last post, and it seems like my boss (head of IT department) changed the RAM to 2 GB yesterday.
I will move the VM to a Server where I have more RAM available and I will try assigning more than 2 GB.
And yes, it increases CPU usage to 100% when I turn on the IMAP service.... really strange.
I will post the results tomorrow. Thank you for your quick help Phoenix, you are awesome
