Build fails with Timeout error ( zOS)

Hi

We are trying to do a initial compile and build for our mainframe modules using RTC eclipse client. We have around 5000 modules to compile and build

Our build fails after few hours with the following error. Should we increase our TIMEOUT or it is due to something else. If we need to increase the TIMEOUT parameter should we update the build definition or anywhere else

Do we need to change any other settings

Below is partial log
