PHP Error showing up on backup firewall (CARP)



  • We have a pair of SG5100 Netgate firewalls and we have them configured for CARP failover and we also have the pfBlockerNG_devel configured to sync via the XMLRPC in settings for pfBlockerNG.

    Our primary firewall doesnt display any issues but out backup/failover one shows 100s of these issues after a week or so. Here is an example of one:

    PHP ERROR: Type: 1, File: /etc/inc/util.inc, Line: 858, Message: Uncaught ArithmeticError: Bit shift by negative number in /etc/inc/util.inc:858
