Here is today's summary of NHC computer operations:
--- Craig Mattocks


1. Reminder: AWIPS II will be upgraded to version 16.1.4 and OPC/HFO will  
back up TAFB starting at about 7:30 AM Monday morning, March 28.

Other items:
1. Bad RHEL 6 Linux kernel: other centers are reporting problems  
(spontaneous reboots of VMs, memory leaks, excessive numbers of sleeping  
processes, crons not running) caused by kernel version 18. If this occurs,  
a Help Desk ticket should be submitted to NCO. Their SysAdmins will roll  
back the kernel on impacted systems to an older, more stable version (12).  
Red Hat has released a new kernel that fixes this problem. NCO will be  
testing this new version next week and, if it is deemed to be stable, they  
will begin a large scale upgrade process across the national centers.
Linux command to check kernel number: uname -r
