[HTCondor-users] condor_dagman crashed when suspend it in 7.8.2 version

[钱晓明 <kyleqian@xxxxxxxxx>]

Hi, I am using Condor for a personal pool, its version is:
$CondorVersion: 7.8.2 Sep 30 2012 Debian-7.8.2~dfsg.1-1+deb7u1 $
$CondorPlatform: X86_64-Ubuntu_ $

I found that to condor_suspend a dagman job can make it crashed and get into RECOVERY mode. This is the output for dagman when issue suspend command:

I think the line in red is the last output before dagman crashed. The terminal window is:

There was also a job disconnect event for this dag node job.

So is dagman crashed?  What should I do? Upgrade my condor software?
