  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Ionic's ISAPI Rewrite

mschultz

New Pleskian
I have an older Windows Plesk 8.6 box running Windows Server 2003 R2. A recent issue we've started experiencing is the plesk(default)(2.0)(Pool) application pool started crashing every few months. I used microsoft DebugDiag to have IIS do a dump when it crashes. According to the dumps, ionic's ISAPI rewrite DLL is causing the crash.

The problem is, the app pool does not automatically restart when this happens, and we do host some sites under it. Could someone help me out with a few questions I have.

1) Since this is an older server, we don't remember if this ionic's ASAPI DLL was installed with plesk, or after the fact. Does anyone know if this was included with default installs of plesk?
2) If it was included, can plesk supply support in resolving this issue?

3) Is there any easy way of tracking down the site that is calling this DLL so we can move it to its own app pool?

4) I guess this should have been first, but, has anyone else experienced this, and is there a solution to the app pool crashing because of this dll.
