Further clarification: I’m now setting up my daemon without using htcondor python binding, and the daemon no longer shows mysterious hang or segfault. From: Xin Wang I was trying to use htcondor to distribute jobs to a pool of machines, and would like to get the job status update and take proper actions as soon as the state update happens. For this purpose, I use htcondor python bindings to implement
a simple daemon. Essentially I use htcondor.submit() to submit tasks, and use htcondor.read_events to read the update. Initially I compiled htcondor 8.6.6 manually to get a python bindings for python 3.6. The daemon worked properly for a couple of hours but then would hang mysteriously at impossible places and I have to use “kill -9” to kill the process
(it does not respond to kill) every single time. The followings are a few examples, and the last line is where the python script hangs. condorserver.py(152): for job in jobs: condorserver.py(153): if job[0].lower() == "submit": _strptime.py(560): return time.struct_time(tt[:time._STRUCT_TM_ITEMS]) condorlog.py(30): if ctime < self.ctime: condorlog.py(34): return now, ctime condorserver.py(236): print("DEBUG-6 add ({}, {}, {}, {}, {}) to updates".format(tag, task, timestamp, tsupdate, status), flush=True) condorserver.py(193): for event in myevents: I sensed that the manually compiled modules may malfunction, so I tried the python bindings installed by RPM. It also had issues. Instead of hanging, it crashed (at a place where a new list is being created in python): condorserver.py(205): print(batch) condorserver.py(206): params = list() *** glibc detected *** python:
