The Application Server (as_server executable) crashes creating a core dump but without any specific specific message in the as_server logfile. 

Pstack of core dump is as follows:

Autosys 11.3 SP1 Incr3_Cum3 on Linux(all)



The application server crashed while retrieving huge agent log file from agent machine.



Implement the LogMaxEndLines variable to control the number of lines transferred from agent to application server to avoid this problem.


  1. Modify/add following line in the $AUTOUSER/config.<instance> file


value:   Defines the maximum number of lines to retrieve from a log file

Default:0, the application server retireves the entire contents of the log file

Limits:  0-10000

Notes:   if the specified value is not in the valid range, the application server resets the value to the default

if the specified value is in the valid range, the application server passes the request to the agent. The agent retrieves the specified number of lines starting from the end of the log file.


2. Enter the following command at the operating system prompt:

kill -HUP applicationserver_pid

applicationserver_pid: defines the process id of the application server that you want to pause and resume.
