Affected Product(s):
BIG-IP APM
Fixed In:
13.1.0, 12.1.3.1
Opened: Mar 22, 2017 Severity: 2-Critical
ECA may be constantly restarting on BIG-IP appliance that has over 24 CPU cores.
ECA NTLM functionality will not be accessible to the users.
-- BIG-IP appliance has over 24 CPU cores or BIG-IP Virtual Edition (VE) platform has over 24 CPU cores. -- APM is provisioned.
If ECA functionality is not required - disable process by running 'bigstart stop eca'. If ECA functionality is needed: 1. Stop eca by running "bigstart stop eca'. 2. Modify file '/etc/bigstart/scripts/eca' as follows: a) Replace line: cpu_count=$(get_number_cpu) with line: tmm_count=$(get_tmm_count) b) Replace line: exec /usr/sbin/${service} -n ${cpu_count} with line: exec /usr/sbin/${service} -n ${tmm_count} 3. Save the file, and restart the process by running 'bigstart start eca'.
ECA no longer restarts when used on a platform with over 24 CPU cores and under 64 CPU cores.
