|Talend Version (Required)||v6.4.1|
|Issue with running platform installer with 8 CPU or more in Windows system|
|Product (Required)||Platform Installer|
Running platform installer 6.4.1 with 8 or more CPU in Windows system throws an error message:
This computer contains 8 logical CPUs. On such configurations, it is necessary to limit the decompression with the command-line option: --parallel-decompression-cores 4 Please re-run the installer with given option.
The 6.3.1 installer runs for a very long time and terminates in the error message "Unable to realloc number bytes".
|Problem root cause||The problem is related to too many decompression threads. Each thread takes about 350 MB of memory, and with 8 threads it requires about 2.8 GB of memory, which is too big for Windows 32-bit (Talend's Windows installer is 32-bit, even for 64-bit Windows).|
|Solution or Workaround||
The installer should be started with the command-line option, limiting the number of decompression threads:
Installer file name --parallel-decompression-cores 4
Talend-Installer-20161216_1026-V6.3.1-windows-installer.exe --parallel-decompression-cores 4
