Issue/Introduction

Customer complained that they are seeing this error intermittently and that WCC is also slow

Error: E131013 Job not collected in WCC. It could mean some problem with monitoring collector.

Environment

Release : 12.0

Component :

Cause

WCC Collector is crashing in a loop because it is running out of memory.  $WCC_INSTALL_LOCATION/collectors/WCC_COLLECTOR/log  folder has some files like this too

Snap.20211007.144700.23238.0004.trc

 

javacore file above has info like this:

Resolution

WCC collector's Java ran out of memory. Increase the memory allocation to WCC and WCC Collector Java. 

 

Our collector memory default settings are below, in /opt/CA/WorkloadAutomationAE/wcc/collectors/WCC_COLLECTOR/conf/wrapper.conf

wrapper.java.initmemory=256
wrapper.java.maxmemory=1024

With r12 onwards, collector is also 64bit and as you are running out of memory, you can easily increase it to much higher (as long as you have enough memory on the WCC server )

wrapper.java.initmemory=1024
wrapper.java.maxmemory=4096

 

The same can be done to increase regular WCC UI's tomcat memory too:

/opt/CA/WorkloadAutomationAE/wcc/tomcat/conf/wrapper.conf

wrapper.java.initmemory=256
wrapper.java.maxmemory=2048

 

bump this up to a higher value like:

wrapper.java.initmemory=1024
wrapper.java.maxmemory=4096

 

Of course, with collector + WCC  now set to 4GB each,  you need at least 10GB free memory on the host before you can use it like this.
