Problem Note 69157: SAS® Web Application Server fails with the SIGSEGV error in libjvm.so
 |  |  |  |
The SAS Web Application Server can fail with a fatal SIGSEGV error due to a bug in the Java Virtual Machine (JVM) garbage collector. When this issue occurs, the SAS Web Application Server process stops and you see messages similar to this in the catalina.out file for the impacted SAS Web Application Server instance:
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007ff4538fca73, pid=3903, tid=0x00007ff3be71a700

If you encounter this issue, you can prevent another similar failure from occurring by adding the following JVM option to the impacted SAS Web Application Server instance:
In Linux environments, you can add this option in the setenv.sh file located here: SAS-configuration-directory/Levn/Web/WebAppServer/SASServerX_Y/bin/setenv.sh
You must add this JVM option within the double quotation marks of the JVM_OPTS="..." line in the setenv.sh file. You must restart that SAS Web Application Server instance to implement that change.
