Set the proxy server initial and upper bound memory limits The proxy server must have a minimum of 4 GB of RAM available (6 GB recommended). The initial and upper bound memory limits determine how much memory the proxy server can consume. In your proxy server directory, open <install dir>/conf/wrapper.conf. Set the proxy server's initial memory limit. Locate the line: #wrapper.java.initmemory=3. Replace it with: wrapper.java.initmemory=6144. Optionally set the upper bound memory limit. Because an upper bound memory limit is not set in the base system, the proxy server may utilize all available memory. If other services are running on the server, you may want to set the upper bound memory limit. Locate the line: wrapper.java.maxmemory=<max_memory_specified_in_MB>. Set the max memory to the desired number. Save and close the file.
