BIGIP one of the best hardware load balancers I used but sometimes the default configuration can’t fit with the way how you do utilize the BIGIP. java.lang.OutOfMemoryError - To mitigate receiving this message, you can use the provision.tomcat.extramb database variable to increase the maximum amount of Java virtual memory available to the tomcat process
Note: F5 recommends an initial increase of 20 MB, but it may not resolve all instances of the error message. If the java.lang.OutOfMemoryError errors continue, repeat this procedure, gradually increasing the value of <MB> until you no longer view the error message
Impact of procedure: Allocating additional memory to Apache Tomcat may impact the performance and stability of the BIG-IP system. You should perform this procedure only when directed by F5 Support after considering the impact to Linux host memory resources.
