[xep-support] Re: GC Overhead Limit Exceeded

Hi Mario, Kevin,

This was dealt with on the DITA Developers GitHub forum:

https://github.com/dita-ot/dita-ot/issues/2415

This is not an XEP issue, it's a DITA-OT and its use of Java issue. To use XEP with the DITA-OT, you need to set both JVM AND maxJavaMemory.

To quote from the thread: The values I used were: maxJavaMemory=1024m and JVM=-Xmx1536m

The default for maxJavaMemory is something like 512m, and it's not enough.

HTH,
David
