Update failed code 137

Description

This error indicates that the update was killed by the operating system due to low available memory on the server.

Error message

Displayed in the collection update logs.

Command finished with exit code: 137

Cause

This indicates that the operating system was running critically low on memory and killed the running process to free up memory.

Resolution

Reduce the memory heap required by the update (gather.max_heap_size and other related max heap size settings) if possible.
Increase the amount of memory allocated to the Funnelback server.
Minimise the chance of multiple updates from occurring concurrently (as each running update will grab a bunch of memory).
