Hey,
any idead what's causing this error?

Kadira: Successfully connected
Kadira: completed instrumenting the app
FATAL ERROR: JS Allocation failed - process out of memory
Cluster: Exiting worker 3 with exitCode=null signalCode=SIGABRT
Cluster: Initializing worker 6 on port 9241

Do you get the same error running on a system/instance with more RAM?

[dnish]

Well, we have 32 GB RAM available and Kadira has shown me a use of 1 GB for our app :/. We have a system with 4 CPU cores.

We've now done some optimizations:

• Reducing worker number from 4 to 2
• Removed a slow publication which increased the CPU usage up to 60% and had a response time over 3 seconds (I think this was the main reason for the crashes)

Now everything seems to work fine, I'll test if the subscription was the problem and we are able to set the worker number again up to 4.
