Large folder issues

**Gawain** · 10-10-2006, 08:40 PM

I'm having some issues when testing with really large folders.

I have imported some 250,000 messages into a folder and both Thunderbird and Evolution only show approx. 8,000 messages and can not do much with the folder. However the messages can all be seen in the web client.

Another problem comes when trying to delete the folder. If I try via the web client I get the dialogue telling me that the operation is taking too long, but nothing happens and if I leave it long enough the session just times out.

Using zmmailbox also has some interesting results

...

Code:

mbox lists@example.com> gf /Inbox/Tech/LKML
{
 id: "260",
 name: "LKML",
 path: "/Inbox/Tech/LKML",
 parentId: "258",
 flags: "u",
 color: "orange",
 unreadCount: 262254,
 messageCount: 262254,
 view: "conversation",
 restURL: null,
 url: null,
 effectivePermissions: null
}

deleteFolder consistently fails without deleting the folder or even partial contents.

Code:

mbox lists@example.com> df /Inbox/Tech/LKML
[] INFO: I/O exception (org.apache.commons.httpclient.NoHttpResponseException) caught when processing request: The server localhost failed to respond
[] INFO: Retrying request

Is there anyway to do the folder delete at a more bare bones level without nuking the rest of the mailbox?

Thanks,

Gawain

Increase the memory allocated to your server process. The "df" zmmailbox operation seems to be causing the server to run out of memory and go down.

Please file this in bugzilla!

Added to bugzilla as bug 11295.

I have tried various values for memory allocation, the machine is running 1.5GB and I have gone as extreme as:
mysql_memory_percent = 10
tomcat_java_heap_memory_percent = 80

It consistently returns an error like this:

Different issue, there. Assuming that it's always complaining about message 561893, it looks like the METADATA column for a row in the database somehow got truncated. (No idea how that happened; I doubt it's related to your earlier problem.)

Since you're deleting the folder anyway, you can probably get away with deleting the relevant row from the database using the mysql command interpreter.

They are just coming out of the wood work at me

My SQL is a whole lot lame, you wouldn't be able to give me an example to work with would you

Kind thanks,

Gawain

Kids, don't try this at home. Or on a production system. Or while zimbra is running.

Figure out the mailbox id for your mailbox:

Code:

SELECT id FROM zimbra.mailbox WHERE comment LIKE '<username>%';

Delete the relevant item row:

Code:

DELETE FROM mailbox<mailbox id>.mail_item WHERE id = 561893;

And force a recalculation of folder sizes on next login:

Code:

UPDATE zimbra.mailbox SET contact_count = NULL WHERE id = <mailbox id>;

Working like a bought one... Thank you Mr Karp
