How to fix the java.lang.OutOfMemoryError exception Follow
The java.lang.OutOfMemoryError exception can be fixed by increasing the memory allocated for Java. To fix the error, identify the particular type of the java.lang.OutOfMemoryError you've got.
Depending on the exception reason, you should run YouTrack with the corresponding start parameter to solve the problem. Please refer to the table below:
| Reason | Fix and Java Parameter | Sample |
| Java heap space | Increase heap size via -Xmx Java start parameter. | -Xmx1g sets allocated heap size to 1Gb |
| Metaspace | Increase MaxMetaspaceSize parameter via -XX:MaxMetaspaceSize. |
-XX:MaxMetaspaceSize=350m |
| GC overhead limit exceeded |
Increase heap size via -Xmx parameter. | -Xmx1024m sets heap space to 1024mb. |
See documentation about Java start parameters for more details.

What about java.lang.OutOfMemoryError: Metaspace ?
"Starting from Java 8, the memory model in Java was significantly changed. A new memory area called Metaspace was introduced and Permgen was removed." - per https://plumbr.eu/outofmemoryerror/metaspace
@Jeff Fritz
Have a look at the documentation here - https://www.jetbrains.com/help/youtrack/standalone/Configure-JVM-Options.html
Initially our installation had set MaxMetaSpaceSize to 250m, but we kept getting
java.lang.OutOfMemoryError: Metaspace
As a workaround I have tried setting MaxMetaSpaceSize to 350m. I'll report back here if this doesn't work.
