Heap Size Error

When I use gpt to process Sentinel-1 data sets.I encountered the following errors.

Invalid maximum heap size: -Xmx5G
The specified size exceeds the maximum representable size.
The JVM could not be started. The maximum heap size (-Xmx) might be too large or an antivirus or firewall tool could block the execution.

My snap software VM parameters are


Cache Size(MB) for SNAP variables is 1024 and benchmark test values are 1024;512;768.

How can I sovle the problems? Thanks in advance.

I have solved :grin:, but my solution is to install 64 bit snap.Because I found a solution in Stack Overflow to regard 32 bit java cannot reserve enough continuous memory.64 bit JVM is indeed OK even though the maximum heap size is -Xmx5G(My conputer’s RAM is 8G).

Thank you all.
