SWA is not reliable

[joako]

What needs to be done to make SWA reliable? I get constant errors and issues like server timed out messages, XML response messages basically I can't keep SWA open all day in one session.

Try upping your Java memory settings in /etc/opt/scalix-tomcat/scalix-tomcat.conf. This solved these issues for us.

Fkienker, what do you have yours set to?

[fkienker]

Using Scalix 11.4.6 on a Dell PowerEdge 2650 with 4 Gb of RAM memory and CentOS 5.5, these settings seem to work best:

JAVA_OPTS="-server -Djava.net.preferIPv4Stack=true -Xms1536m -Xmx1536m"

Going higher than 1536m causes subtle and annoying problems with Scalix WebAccess.
Also, upping the txqueuelen to 5000 helps a lot. Use something like:

/sbin/ifconfig eth0 txqueuelen 5000

to set it so you can try it out. If it helps, add it to something which will survive reboots. On CentOS or RHEL this is the /etc/rc.local file.

Best regards,
Fred

thanks, hopefully this makes the users who use webmail a little happier.

Sadly moving the execs to that mail server which shall not be named, the lag of outlook 2010 support and not stable BES and activesync support forced our hand. Hopefully we can one day move them back. For me on my Droid 1 activesync works great, so it seems highly dependent on the client implementation.

Well I increase the memory from the default and I still get timed out errors. If I do nothing, not even click ok on the massage the folder eventually loads.

Most of the times the slowness is related to how swa retrieves messages from the mailstore.
In my experience all performance issues were bound to improper functioning of the Postgres backend.

Have you examined your /var/opt/scalix/xx/tomcat/logs/scalix-swa.log for errors ?

[joako]

So what is the correct way to configure Postges and the mail store? Right now I have everything at the default.

[BaldBoy]

Postgres "should" be set by default ... but sometimes it happens it gets misconfigured.

Please post here any error you find in the /var/opt/scalix/xx/tomcat/logs/scalix-swa.log

I am seeing messages such as:

But they don't seem related to a Postgress or mailstore misconfiguration.

[BaldBoy]

I'd suggest you the reading of this thread: http://www.scalix.com/forums/viewtopic.php?t=11436
(same error as yours).

Probably your configuration is pointing to 127.0.0.1 instead of the IP address of ethernet adapter.

Regards.

Is it slow for everyone, or just for people with extremely large numbers of e-mails in the top-level of the inbox.

I haven't seen it recently, but the data integretiy issues persist.
