It would be great if you can add another check into the prechecks performed in the installation on Linux with

This check should be for the maximum number of process for the user hpdp. 

In one environment I helped to upgrade all the installations hungs for so much time and also have problems with the GUI after some time of usage. 

The problem was this configuration because the server had this value in 1024. 

The server.log reports this error:
23:39:28,848 ERROR [ChannelListeners:94:default I/O-47] XNIO001007: A channel event listener threw an exception: java.lang.OutOfMemoryError: unable to create new native thread

I installed it in another server with the value in 4096 and works with no issues. 

The value is saved here in /etc/security/limits.conf or /etc/security/limits.d/90-nproc.conf in RedHat: 

hpdp       hard    nproc     15000


  • Hi ,

    You have my vote. This kind of lessons learned should be integrated into the pre-flight scripts executed by the setup process. Something similar was done for nofiles in A.10.40 so this should be easy to implement.
