Error after running server for a while

[Mainz]

Hello,

I have a Mailserver based on Postfix, Dovecot, Postgrey, Postfixadmin, Apache, Mysql.
When my server runs for some days i get the following error and nothing works anymore.

swap_pager: indefinite wait buffer: bufobj: 0, blkno 25691, size: 4096

I have absolutely no idea what it comes from. So I don't have any idea which logs are required to post here. Please tell me.

System Hardware

• 512 MB RAM
• 50 GB Harddrive
• 1 Core CPU

This is my swapinfo after a fresh restart of the system.

Thanks i checked the thread but it didnt help. I checked some logs that looks like sshd is the reason. so i stoped the service and watched what happend.
Now the following is happend after ca. 24 hours.

It looks like there are some issues on the virtualization host itself.
