[Dxspider-support] Daily user disconnections

[Lee Sawkins]

You might not like to hear this, but HRD is the source of my frequent user disconnects. My HRD users are coming and going all the time. I have complained about this before, but nothing has ever been done. It appears if the node does not reply to HRD immediately the program will disconnect. ALL other user client programs are stable and do not do this.

I don't have that line in my crontab... but I still have frequent user disconnections. I haven't yet figured it out.

It's been bugging me for a while that ei7mre seems to kick off users every day, despite the cluster remaining running 
Today I did a bit of digging and this seems to coincide exactly with the cronjob that is run by the system from 
cmd/crontab at 3AM 
the offending entry appears to be 



0 3 * * * Spot::daily() 


is this because the job called is taking too long and it's in the main thread? or do I have a problem elsewhere I should be investigating? 
Do I risk really messing things up if I change the schedule of this job to run at a time when I might be awake, to allow me to do a bit more debugging 


ei7mre runs on a Centos7 VM with adequate resources (20G of SSD backed Storage, 1G ram) and the dxspider process never actually crashes (up-time is 250 days at present) 
ei7mre typically has ~ 140 Users at weekends these days and never feels in the least bit sluggish, very light CPU load (0.04) most of the time
