Issue/Introduction

My JasperSoft Server 7.1.1 for External CABI for UIM tomcat crashes every day.

Looking at the tomcat log, you can see the errors piling up starting from Dec 8th 11:27, around the time the integration was setup.

Catalina.out

2020-12-07 14:51:31,258 ERROR RenderViewExceptionInterceptor,http-nio-8080-exec-4:55 - Internal server error occurred. Please contact your system administrator.

------------------------------

 

Additional info:

•  Reinstalled the CABI - Same behaviour there, the server runs fine for a while and then the tomcat crashes

•  Customer seeing the same issue on three different environments that are crashing.

•  CABI also crashes even when the cabi_external probe is deactivated.

•  Removing the dashboards does not help. 

•  Both JRE_HOME and JAVA_HOME server variables pointing to the jre provided with Broadcom's CABI Jasper Report Server installation: 
/opt/CA/SharedComponents/CABI/jre

Environment

UIM 20.3.1
CABI external probe 4.20
CABI 7.1.1 on CentOS Linux release 7.8.2003 (Core)
Bundled postgresql

Cause

•  this issue could because of RAM Memory space available

Resolution

•  Check whether you have the RAM space available(based on the Xms and XMX values). 

•  Check whether you have "setenv.sh" file in ../CA/SC/CA Business Intelligence/apache-tomcat/bin folder.

 

add "-Djava.awt.headless=true" to the setenv.sh file like below : 

 

-Djava.awt.headless=true parameter should be added in the same file in JAVA_OPTS parameter value after the license directory.

 

So, it should be something like this:

 

 JAVA_OPTS="$JAVA_OPTS -Djs.license.directory=../webapps/jasperserver-pro -Djava.awt.headless=true"
