Known Issues

Scheduling and running simultaneous system backup tasks negatively 

impacts system performance. As a workaround, stagger your scheduled 

tasks so only one backup runs at a time. (134575/CSCze89679)

If you edit a previously-configured LDAP connection where user and group 

access control parameters are enabled, clicking Fetch Groups does not 

populate the Available Groups box. You must re-enter your password when 

editing an LDAP connection in order to fetch available groups. 

(134872/CSCze89834)

In some cases, if you enable Resolve IP Addresses in the Event Preferences 

section of the Event View Settings page, hostnames associated with IPv6 

addresses may not resolve as expected in the dashboard or event views. 

(135182/CSCze90155)

You cannot enter more than 450 characters in the Base Filter field when 

creating an LDAP authentication object. (135314/CSCze89081)

In some cases, if you schedule a task while observing Daylight Saving Time 

(DST), the task does not run during periods when you are not observing 

DST. As a workaround, select Europe, London as your local time zone on the 

Time Zone Preference page (Admin > User Preferences) and recreate the task 

during a period when you are not observing DST. (135480)

The system requires additional time to reboot appliances running Version 

5.3 or later due to a database check. If errors are found during the database 

check, the reboot requires additional time to repair the database. (135564, 

136439)

In some cases, the system may generate a false positive for the SSH 

preprocessor rule 128:1. (135567/CSCze89434)

If you apply an intrusion policy containing a rule with the Extract Original 

Client IP Address HTTP preprocessor option enabled, the system may 

populate intrusion events with incorrect data in the Original Client IP field if 

traffic passes through a dedicated proxy server. (135651/CSCze89056)

If the maximum transmission unit (MTU) setting on an 8000 Series 

managed device triggers IP datagram fragmentation, the system may 

experience NMSB connection issues. (135731/CSCze89504)

If you schedule a task with Report as the job type, the system does not 

attach the report to the emailed status report. (136026/CSCze90265)

If you apply an access control policy to multiple devices, the Defense 

Center displays the task status differently on the Task Status page, the 

Access Control policy page, and the Device Management page of the web 

interface. The status on the Device Management page (Devices > Device 

Management) is correct. (136364/CSCze87068, 136614/CSCze89936)

In some cases, if you create a custom workflow based on the health events 

table, the Defense Center displays conflicting data in the event viewer. 

(136419/CSCze90336)

If you import a custom intrusion rule as an 

.rtf 

file, the system does not 

warn you that the .

rtf 

file type is not supported. (136500/CSCze89991)
