Siebel 18.12 Multiple Component Crashes Happening Spite of No Changes Made to Siebel Configurations or Settings (Doc ID 2591059.1)

Last updated on JANUARY 03, 2023

Applies to:

Siebel CRM - Version 18.12 and later
Linux x86-64


No changes were performed to Siebel settings, no Siebel patches of any sort, but there are multiple components getting terminated.
The environment is not usable and cannot stay running for more than 5 minutes.
Restarting the environment is not helpful to resolved the situation.

strace was obtained by modifying the siebmtshw shell script located under siebsrvr/bin directory as follows:

a) Take backup copy of the siebmtshw shell script for safety reasons
b) Replace the last line:


        exec siebmtshmw $@


        strace -t -v -f -s 2048  -o siebmtshw_strace.$$ siebmtshmw $@

c) Save the file
d) Restart the Siebel Server
e) strace logs will be generated under siebsrvr/bin

Prior to the SIGABRT the preceding error found in strace log file highlighted below.
