Tuxedo WSH Process Getting Errors, Memory Size Increasing, Core Dumps, And Requires A Restart Of The Tuxedo Application (Doc ID 2222382.1)

Last updated on JUNE 08, 2023

Applies to:

Oracle Tuxedo - Version 12.1.3 and later
Information in this document applies to any platform.

Symptoms

On : Tuxedo Version 12.1.3.0.0, 64-bit, no rolling patch installed

Large WSH processes grabbing all the cpu resources:

CPU TTY PID USERNAME PRI NI SIZE RES STATE TIME %WCPU %CPU COMMAND
0 pts/3 11450 webadm 235 20 82744K 3580K run 199:46 101.04 100.87 WSH
30 pts/3 15429 webadm 241 20 82616K 3516K run 619:31 101.01 100.84 WSH

Then have to restart tuxedo.Happening every 6 hours. Installing rolling patch RP078 did not help.

Errrors in ulog prior to a WSH crash are similar to the following:
