SAP Note 15766 - Process crashes due to signal receipt (core)

Symptom:

Entry in SysLog (Q0E): Signal $$$ received from operating system (core)

Cause and prerequisites

A process received a signal from the operating system (e.g. due to a memory protection error) that caused the process to terminate with dump (core).

Solution
To analyze the problem, you must first analyze the dump. The primary item of interest for SAP is the context (C stack) in which the signal was received. This C stack can generally be found in the trace file of the process affected (dev_w*). Only if there is no C stack there or the existing C stack is unusable (e.g. due to entries such as NONAME) is the file core required for further analysis.

The dump is placed in the work directory /usr/sap//DV*/work under the name "core". First make a backup copy of this file (mv core core.sav).
If you are able to determine the C stack yourself, using a symbolic debugger such as xdb, dbx, etc., it will save a lot of time if you can print it out and send it directly to us in Walldorf.
Otherwise, please establish an X.25 link to Walldorf, which will enable us to analyze the dump in your system.
