Listener Crash with Core Dump due to Cross Registration
(Doc ID 877663.1)
Last updated on JANUARY 17, 2020
Applies to:Oracle Net Services - Version 18.104.22.168 to 22.214.171.124 [Release 8.1.7]
You may have 8i and 9i oracle instances registering with 8i listener .
For example :
Lets say you have oracle 8.0.6 , 126.96.36.199 and 188.8.131.52 instances running on the same box and all registering with 8.1.7 listener.
The setup seems to work fine for couple of days , but in the long run you may see the 8.1.7 listener crashing intermittently .
You may also notice the listener crash generates core file. The core file will be usually generated in the directory where the tnslsnr executable exixts.
The stack taken out of the core file may look like below :
We can see the 'tnslsnr' terminated with signal 11 (segmentation fault) . The default action of a process after receiving this signal is to terminate . Hence the listener crash.
