• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

IOWait - Plesk 7.5 Reloaded

I'm running Plesk 7.5 Reloaded on a RedHat ES system. It has been running acceptably for the last couple of months but lately I've been getting a lot of user complaints about e-mail delivering slowly (i.e. someone sends an e-mail to a user while they're having a phone conversation and the mail takes 2-3 hours to appear).

The only thing I've been able to find that looks abnormal is IO Wait. This is a dual-CPU hyperthreaded machine, so "top" reports 4 CPUs. Two of the reported CPUs are always sitting with a very high IO Wait count. The machine is showing as spending close to 50% of it's time in IO Wait.

I'm not seeing hardware error messages in /var/log/messages or dmesg.

Any suggestions as to what might be causing this?
