If you encounter this error on the j5 reporting service, do the following:

  1. Run C:\Program Files (x86)\j5\framework\reporting-service\bin\j5ReportingServicew.exe. The j5 Reporting Service Properties window opens.

  2. Select the Java tab.

  3. Increase the memory available in the Maximum memory pool box.

    Since the j5 reporting service is a 32-bit process, the theoretical maximum value is 4GB. However, due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern Windows systems the maximum heap size ranges from 1.4GB to 1.6GB.
