all jobs (webi instance promotion job, publicatiion...) are time consuming to start

Hi expert,

I have a problem with a new installation of SAP BI4 SP5 patch 3 in AIX OS with 24 GO memory and 4 core cpu.

all work well,  only a jobs ( all kind of jobs promotion, scheduling webi, publication...) take many time to start

I have did many action but they did not solved my issue

1. Duplicate APS and AJS
2. Create a new APS and AJS
3. Create a new SIA with default servers
4. Increase the number of Max concurent jobs in AJS to 15

I have the issue in both DEV and QUAL servers.

Any idea please
