<div>Hi Yuvi!</div>
<div> </div>
<div>Many toollabs users do start cron jobs to grid engine 00:00 UTC. Isn't it possible, to start earlier and to end the downtime before 00:00 UTC?</div>
<div> </div>
<div>Thank you,</div>

<b>Betreff:</b> [Labs-l] [Labs-announce] [Tools] GridEngine maintenance - 27 Jan 2016, 1800-0200 UTC</div>
<div name="quoted-content">Impact summary:<br/>
<br/>
The Gridengine queue requires maintenance that may invalidate<br/>
currently running jobs. We will perform this maintenance 1/27/2016 at<br/>
1800-0200 UTC.<br/>
<br/>
Over the course of the last few weeks we have experienced periodic<br/>
crashes of the Grid Engine master. We have resolved issues<br/>
surrounding multiple master processes accessing the same queue file.<br/>
Unfortunately, this has not resolved the underlying corruption.<br/>
We will attempt to dump and rebuild the queue as-is to minimize user<br/>
impact. If this process is unsuccessful we will have to start a fresh<br/>
queue. Once the<br/>
queue has been rebuilt we will be doing a rolling restart of<br/>
exec/webgird nodes to refresh job associations with the master<br/>
process.<br/>
<br/>
This is part of our ongoing work to stabilize the Gridengine setup.<br/>
<br/>
Thanks for your patience,<br/>
<br/>
Labs Team<br/>
