[HTCondor-users] Nodes CentOS7 fail to run jobs

[Almudena Montiel <almudena.montiel@xxxxxx>]

Hello

we are in the process of migrating the nodes to CentOS7.

We find that jobs stay IDLE, but there are nodes available in C7.

In the nodes I can see:

==> /var/log/condor/StartLog <==
01/28/19 10:41:43 slot1: Changing activity: Idle -> Benchmarking
01/28/19 10:41:43 BenchMgr:StartBenchmarks()

reset by peer
01/28/19 10:51:46 Buf::write(): condor_write() failed


In the SchedLog of the central node I see that jobs are being rejected:

An excerpt:

01/28/19 11:02:08 (pid:46843) Negotiating for owner: 
group_atlas.admin.atl105_score@xxxxxxxxx

01/28/19 11:02:08 (pid:46843) Activity on stashed negotiator socket: 
<150.244.244.86:22808>

Please, could you help me debugging what could be the issue?
