fw_workers process consumes high CPU on the Standby member of a ClusterXL.
High number of entries on fw tables which are performing local sync. the tables which perform local sync can be seen using the following command (from Expert mode):
# fw tab | grep 'local sync' -B 1 | grep -v 'local sync' | awk 'NF {print $2}' | xargs -i fw tab -t {} -s
For example:
[Expert@GW-1:0]# fw tab | grep 'local sync' -B 1 | grep -v 'local sync' | awk 'NF {print $2}' | xargs -i fw tab -t {} -s

Cause
By default the 'local sync' interval mechanism of the Standby member is different from the 'local sync' interval mechanism on Active member. The interval on the Standby member is much lower which cause it to preform local sync more often.
