QStudio - Out of Memory Error

OutOfMemoryError: Java heap space

If you get an error such as this:

Stack=java.lang. OutOfMemoryError: Java heap space at kx.c.r(c.java:632) at kx.c.r(c.java:593) ....... at kx.c.k(c.java:980) at com.timestored.kdb.CConnection.query(CConnection.java:89) at com.timestored.qstudio.model.QueryManager.sendQuery(QueryManager.java:289) ...

A query sent to the server has returned a large object and while trying to convert that result to a java object the program ran out of memory. There are two things you can try:

1. Increase the memory java is allowed:
   • Windows Instructions
   • Custom Command Line Arguments (Find the .jar file in c:\program files...../timestored/)
2. Reduce the memory QStudio uses by reducing the max object size and the history size (see screenshot below)
