Hi Champs,
I am having this issue also and my DS version is 4.2 SP1
al_engine -v = SAP Data Services Engine Version 14.2.1.656
FourPart = Designer - 14.2.1.622, JobServer - 14.2.1.656, JobEngine - 14.2.1.622, Repository - 14.2.1.0000.
RedHat - Linux az18u8667 2.6.18-406.el5 #1 SMP Fri May 1 10:37:57 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux
Intermittently daily we are having issue where the job server crashes and OS garbage collection process gdb takes up all of the server resources which then requires a hard reboot.
Any help would be very much appreciated.
