Release Notes Docs Status: Added: Documented as Resolved Issue Writer: Added: dlesage Release Notes Text: Added: https://issues.jboss.org/browse/SOA-3490 Note that the 32-bit version of the Windows operating system is no longer a supported configuration. However, if you are continuing to run 32-bit Windows, it is worth being aware that with the default settings, very little memory in the process' address space for thread stack and other allocations (by default on Windows half of the address space is reserved for the system). This results in this type of error when you run SOA: java.lang.OutOfMemoryError: requested 842040 bytes for Chunk::new. Out of swap space? To fix this, you can decrease heap or configure a smaller thread stack size (such as -Xss128k). You could also try to change the partitioning of the process space. Added to release notes. |
Affects: Documentation (Ref Guide, User Guide, etc.), Compatibility/Configuration project_key: SOA We have two things to document here. One is that windows 32bit is dropped from supported configurations. The other thing to document is that to run server "production" or "all" with EDS installed on windows 32bit machine the default memory settings are too aggressive. {noformat}-Xms1303m -Xmx1303m -XX:MaxPermSize=256m{noformat} With 1,5G allocated memory for heap and permgen, there is only very little memory in the process' address space left for thread stack and other allocations (by default on windows half of the address space is reserved for the system). This results in an error similar to the below one: {noformat}java.lang.OutOfMemoryError: requested 842040 bytes for Chunk::new. Out of swap space?{noformat} To fix this, you can decrease heap or configure smaller thread stack size (e.g. -Xss128k), or try changing process space partitioning [1].
