(Doc ID 2319824.1)

Last updated on NOVEMBER 18, 2017

Applies to:

Siebel CRM - Version 15.0 [IP2015] and later
Linux x86-64

Symptoms

Recent version of Oracle Linux 7.x and 6.x may have UEK 4.1.12.x as their kernel.

When they are upgraded to the latest kernel (4.1.12-103.7.3.el7uek.x86_64 as of 10/20/2017), Siebel Server does not start up correctly. Behavior should look like one of them.
1) start_server script never completes. siebsvc process for Siebel Server is not created.
2) start_server script finishes and siebsvc process for Siebel Server is created. However any other child processes are not created. If system monitor has been running before start_server, it displays the status of siebsvc process as "uninterruptible".

In any of cases, there are several other issues.
- Terminal windows cannot be started.
- ps command never returns.
- poweroff command may not work so that hardware reset is necessary.

This behavior has been observed on several Siebel version, including IP2017, IP2016 and IP2015. Although other Siebel versions are not tested, the same behavior is likely to occur.
