Informix Error -5010: CSM: internal processing error.

Cause and resolution

CSM: internal processing error.

A CSM (Communications Support Module), in the database server or in the client, detected an internal processing error and is incapable of self-diagnosing it to provide additional information. This error can occur only during use of a CSM and normally represents an internal processing error, but could be caused by an undetected protocol error.

If this error occurs during context setup (that is, at connection time), the connection establishment fails. If this error occurs after establishment of the connection, the connection is dropped.

Contact IBM Informix Technical Support or the CSM vendor and have the following information available: CSS configuration files and sqlhosts information for both the client and the database server.

Reasons / Common Causes

-5010 fires when a CSM (Communications Support Module) detects an internal processing error it can't self-diagnose — per the official guidance, this normally represents an internal processing error, but could be caused by an undetected protocol error.

  1. An internal CSM processing fault, per the official guidance — the general cause.
  2. An undetected protocol error, per the official guidance — a possible, named alternate cause.
Solutions / Resolution
  1. Contact IBM Informix Technical Support or the CSM vendor, per the official guidance, with the CSS configuration files and sqlhosts information for both sides available. Per the official guidance, if this occurs during context setup, the connection fails; if after establishment, the connection is dropped.
