8/5 22:42:37 Our parent process (pid 16496) went away; shutting down
8/5 22:42:37 Got SIGTERM. Performing graceful shutdown.
I don't know who is this "parent process" : there was only thre daemons : collector (16497), negotiator (16498) and shedd (16499)
The parent process is the condor_master. From the log file you sent, it looks like it exited silently. Did you possible kill that process with "kill -9"? Did anything happen to your computer at 8/5 22:42 that could have killed the master?
Has someone an explication ? Is there an option to set, so the daemons never exited ?If some external process or person didn't kill the condor_master, then the it shouldn't exit.
Is there a core file for the condor_master? If so, that would indicate that it crashed. You can usually find the core files for the daemons in the same directory as the log files.
