Description (partial)

On Nexus 3000 we might see high usage of system flash due to "hwclock" core files in "/var/sysmgr/work":

Nexus# show system internal flash 
Mount-on                  1K-blocks      Used   Available   Use%  Filesystem
/var/sysmgr                  921600    921600           0    100   none

This can generate error messages or ISSU will not proceed.

This issue might be seen after upgrade of the N3k device if time settings are corrupted during the upgrade:
