Description Matthew Farrellee 2012-03-29 17:05:16 UTC

Description of problem:

The condor_startd allows a reconfig to change its slot configuration. If a job is running during that reconfiguration, the startd will crash.


Version-Release number of selected component (if applicable):

Likely all, definitely 7.6.7-0.8.


How reproducible:

100%


Steps to Reproduce:
0. Enable partitionable slots

 SLOT_TYPE_1=cpus=100%
 NUM_SLOTS=1
 NUM_SLOTS_TYPE_1 = 1
 SLOT_TYPE_1_PARTITIONABLE=true

1. service condor start

2. echo 'cmd=/bin/sleep\nargs=1d\nqueue' | condor_submit

3. Wait for job to start running

4. Disable partitionable slots

 #SLOT_TYPE_1=cpus=100%
 #NUM_SLOTS=1
 #NUM_SLOTS_TYPE_1 = 1
 #SLOT_TYPE_1_PARTITIONABLE=true

5. condor_reconfig


Actual results:

In MasterLog -

 The STARTD (pid 10060) died due to signal 11 (Segmentation fault)

In StartLog -

 Stack dump for process 10060 at timestamp 1333040167 (10 frames)

Expected results:

No crash.

MRG-Grid is in maintenance and only customer escalations will be considered. This issue can be reopened if a customer escalation associated with it occurs.
