In an MPLS environment for QFX5K, error messages with error code '-11: Operation failed'
may be observed intermittently. This article indicates what causes these error messages to be logged and whether any action is required to address the error logs.
The following messages are observed in the log messages:
May 18 28:03:56 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439148with error (-11:Operation failed)
May 18 28:05:38 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439164with error (-11:Operation failed)
May 18 28:07:13 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439180with error (-11:Operation failed)
May 18 28:08:37 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439196with error (-11:Operation failed)
May 18 28:10:17 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439212with error (-11:Operation failed)
May 18 28:10:23 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439228with error (-11:Operation failed)
May 18 28:11:20 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439244with error (-11:Operation failed)
May 18 28:12:39 2020 JTAC-SWITCH fpc0 brcm_mpls_tunnel_switch_add: stat group create failed for label 439260with error (-11:Operation failed)
The above error can also be seen as:

Jan 5 20:50:05 2019 JTAC-SWITCH fpc0 brcm_mpls_label_stat_get: pkt stat counter get failed for Label 440860
Jan 5 20:50:05 2019 JTAC-SWITCH fpc0 brcm_mpls_label_stat_get: pkt stat counter get failed for Label 440876
The error code "-11 (Operation Failed)
" is due to exhaustion of the stats counters related to the MPLS route entry from the dedicated pool of counters.
These log messages are related to the stat counters. They do not have any impact on service and can be safely ignored.
