Hi @vplesca,

@bobj

You need to tweak your memory settings somehow/somewhere. Where
exactly depends on how much RAM you have free on the machine and what
other processes might be running and using memory and how you have
setup tomcat.

Possibly you need to increase the size of Xmx (heap space) in your
java options. Or you might need to remove or scale back something
else which is running on your machine.

Java heap space] with root cause java.lang.OutOfMemoryError: Java heap space

@Gassim

• The system cannot find the path specified.
  It might help to increase the java heap space to (-Xms4096m -Xmx4096m).
  change to java.exe -Xms4096M -Xmx4096M¡± (source)

Please check the Catalina.out log file, would you share it with us (without the sensitive info)? Please check if there any tables that need to be dropped or taking too much space.

Thank you!
