Hotfix: NetBackup Master Server Policy Execution Manager (nbpem) and Client fixes to address issues when Daylight Savings Time (DST) changes take place at midnight [from 11:59:59 PM to 01:00:00 AM]
A Hotfix is available for NetBackup 7.7.3, 8.0, and 8.1 which resolves the following issues.
BugID - ET3935542 - [Master Server]
The NetBackup Policy Execution Manager (nbpem) consumes high CPU, loops, and fails with status 196 in certain time zones if a calendar-based backup schedule is due on a day on which daylight savings time moves the time forward from midnight to 1:00 AM. More details in Article 100032172.
BugID - ET3932565 - [Client]
Hosts located in time zones where daylight savings time changes at midnight initiate a large number of
bpclntcmd -clean_old_logs commands on the day before the daylight savings change occurs. This exhausts memory and CPU capacity. These are seen in the bpcd process log located at: Windows <installpath>\NetBackup\logs\bpcd or Unix/Linux: /usr/openv/netbackup/logs/bpcd
00:03:11.694  <2> setup_debug_log: switched debug log file for bpcd
00:03:11.694  <16> clean_old_logs: bpclntcmd fork pid = 198366
