### Symptoms:

On a (multi) project snapshot with issues creation Configuration Manager fails with an error similar to this.


### Cause:

This can happen in case the system contains issue data that is disproportionate to the amount of system memory / heap size allocated on the environment. Refer to Atlassian's Jira sizing guide  [https://confluence.atlassian.com/enterprise/jira-sizing-guide-461504623.html](https://confluence.atlassian.com/enterprise/jira-sizing-guide-461504623.html) 

Note that creating a  very large snapshot (e.g. of projects with tens of thousands of issues) may also require additional memory to be allocated for the heap.

### Resolution:

Refer to the following [article](https://confluence.atlassian.com/jirakb/jira-applications-crash-due-to-outofmemoryerror-gc-overhead-limit-exceeded-213518857.html) and more specifically to [increasing JIRA application memory](https://confluence.atlassian.com/adminjiraserver070/increasing-jira-application-memory-749383419.html) for instructions how to resolve this issue.
