Informix Error -955

-955 Remote host could not receive data from client.

This internal error reflects a failure in communication between your application and the Informix STAR or IBM Informix NET software at another site. Restart your application. Look for operating-system messages that might give more information. If the problem recurs, ask your network administrator to run network diagnostics. If the error recurs, note all circumstances and contact IBM Informix Technical Support. This message appears prior to Version 6.0.

-955 Database server could not receive data from client.

This internal error reflects a failure in communication between your client application and the database server software at another site. Restart your application. Look for operating-system messages that might give more information. If the problem recurs, ask your DBA to run network diagnostics. If the error recurs, note all circumstances and contact IBM Informix Technical Support. This message appears beginning with Version 6.0.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-955 fires when communication between the client application and the server software at another site fails — per the official guidance, an internal error, in the same general family as -918/ -932, with the escalation path pointing at either the network administrator (pre-6.0, framed around Informix STAR/NET) or the DBA (Version 6.0+, framed around the database server directly).

  1. A genuine internal communication failure between the client and remote server software, per the official guidance's framing.
  2. Network instability or congestion severe enough to break the data transfer, the same general category as -912/-913/-918/-932.
Solutions / Resolution
  1. Restart your application, per the official guidance — the documented first step.
  2. Look for OS-level error messages that might give more information, per the official guidance.
  3. If the problem recurs, ask your network administrator (pre-6.0) or DBA (Version 6.0+) to run network diagnostics, per the official guidance — note the escalation target shifted from network administrator to DBA between these version ranges.
  4. If the error still recurs, note all circumstances and contact IBM Informix Technical Support, per the official guidance.
Examples
N/A

An internal client/server communication failure at another site — restart first, then escalate per the version-appropriate path (network administrator pre-6.0, DBA on 6.0+).

Diagnostic Checks
  1. Restart the application first.
  2. Check OS-level error messages.
  3. Escalate to the network administrator or DBA, depending on server version, if it recurs.
Related Errors / Related Topics
  • -918 — "Unexpected data received from another database server." A related internal protocol-level error, at another site, on the receiving end of this same general failure mode.
  • -932 — "Error on network connection, function system call failed." A related network/system call failure, with additional platform-specific (Windows Sockets, ASCL) checks.

Same escalation pattern as -918/-932 — restart first, then network diagnostics via the version-appropriate contact (network administrator pre-6.0, DBA on 6.0+).
