We have been witnessing unintended restarts of the nodes. 

 

 

Layer 7 64bit Virtual Appliance - Version 8.0  50 GB disk 2 GB RAM 2 CPU

- Virtual CPU's 4

- Real Memory - 2 GB

- Logical disk size - 50 GB

- CPU core clock frequency 2.8 GHz

 

As per the CA API Gateway 9.1 recommendations, we are planning to increase the memory to 4 GB.


Minimum requirements for a host machine running the Software form factor of the CA API Gateway:

Requirement Minimum
Networking one IPv4 or IPv6 interface
Processor Dual core processor, 2 GHz or faster
Memory 4 GB (8 GB or above recommended)
