Scalix Forums

Hello,

I have a scalix 11 Community server on Redhat AS 4. this server has about 500Users and the configuration is PIV 2GB with 400GB mirrored Drive.

Ever since this systems is made live I have noticed that every week the system startes to slow down , some times local delivery service stops, opening SAC becomes extremly slow. Even SSH to server is very slow. I eventually restart the server . After the restart everything works fine for about a week then again the server starts to slow down.

Any insights.

Sanjay

Can you give us any idea what generates the load? I.e. to know what top process shows up in the top output or so. Also, for local delivery, if you say it stops, what does omstat -s show for it's status? If it is in Aborted state, are there any indications why that's the case in omshowlog?

Florian.

Hello florian,

Here is the Event log from SAC for local delivery.

this looks like message store corrupion. Unfortunately, it does not point to a particular user. So you're probably best off to run the



command to check and potentially repair consistency of your message store at the next possible occasion. You can do this while the system is being used, just be aware that there will be additional load and it might have performance implications for your users.

Cheers,
Florian.

You could also look in the Service router audit log and search for that message-id, that may help identify the recipient(s). Then run an omscan against those user(s) as Florian suggests.

I continue to have the server slow down issue and local service failing.

I get this error in my local Delivery

Hello, I'm having the same issue, has anyone been able to figure out what seems to be the problem? I tried the Omscan but it lasted a couple of days OK then slowliness again. Thnx.
