My VPS has:

1024MB RAM

5GB Space

I have over 500 Users and there are 50-100 users online at the same time.

The probleme is, that server memory is full after 1-2 days and I have every time to send ticket to my provider, that they restart the server. I can’t access to SSH or Openfire Admin Console.

Is there anyone with the same problem? Or does anyone knows how to fix it?

Thanks!

Hi,

with “-Xmx128m” your Openfire server will likely never use more than 512 MB so I wonder which other products run on your VPS. You could restart Openfire daily anyhow I wonder whether this does help.

There nothing special on the VPS. I have fresh installed OS and all what i installed is openfire and MySQL.

Here is my /etc/default/openfire file:

You see, there is nothing special, but java overtakes 694m memory!

Hi,

you may want to add a swap partition with 1 - 2 GB, this should help a lot.

Hi,

I tried this already. But after some research I noticed, that it’s impossible to add swap into a VPS. It’s blocked.

mkdir /swap

dd if=/dev/zero of=/swap/swapfile bs=1M count=1024

1024+0 records in

1024+0 records out

1073741824 bytes (1.1 GB) copied, 2.02027 s, 531 MB/s

chmod 0600 /swap/swapfile

mkswap /swap/swapfile

Setting up swapspace version 1, size = 1073737 kB

no label, UUID=8d89b70c-2522-4b88-b7eb-08a62fb5ecb6

swapon /swap/swapfile

swapon: /swap/swapfile: Operation not permitted

Any ideas?

Hi,

ask your VPS provider.

You could try to use a 32bit JVM which may be more friendly in allocating virtual memory.

If the problem occurs after a couple of days, there’s a chance that you’re running into a memory leak. Lately, a memory leak related to PEP (a part of Openfire) has caused quite some problems on networks on which at least one user uses the Empathy client.

You’ll find more information and a work-around here: Openfire 3.6.4 memory leak with Empathy
