Hi All, *Scenario* We have a cluster of two SRX550 and a MX5-T router. An aggregated link (LACP) is connecting node0 (primary node) of SRX 550 cluster to MX5-T router. The aggregate link consists of two ports. Copper/Ethernet.
The devices are in the same rack and directly connected (in case someone doubts the physical connectivity) *Junos* SRX550 Cluster 12.1X44-D30.4 MX5-T 11.4R7.5 *Problem* Sometimes it is observed that the LACP goes down on the MX5-T router. At that time following logs are seen. LACPD_TIMEOUT: ge-1/0/4: lacp current while timer expired current Receive State: CURRENT /kernel: KERN_LACP_INTF_STATE_CHANGE: lacp_update_state_userspace: new state is 0 cifd ge-1/0/4 /kernel: KERN_LACP_INTF_STATE_CHANGE: lacp_update_state_userspace: new state is 0 cifd ge-1/0/5 /kernel: ae_bundlestate_ifd_change: bundle ae1: bundle IFD minimum links not met 0 < 1 At this time, the SRX cluster tries to failover and following logs appear. jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 2 transitioned from 'secondary' to 'primary' state due to Remote node is in secondary hold jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 1 transitioned from 'primary' to 'secondary-hold' state due to Monitor failed: IF jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 2 transitioned from 'primary' to 'secondary-hold' state due to Monitor failed: IF jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 1 transitioned from 'secondary-hold' to 'secondary' state due to Back to back failover interval expired jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 1 transitioned from 'secondary' to 'primary' state due to Remote node is in secondary hold jsrpd[1393]: JSRPD_RG_STATE_CHANGE: Redundancy-group 2 transitioned from 'secondary-hold' to 'secondary' state due to Back to back failover interval expired Minutes later, the node0 comes back as primary and service is restored. Besides, following logs on the SRX550 are coming. /kernel: Process with Most Children- 1:init - Children - 211 /kernel: maxproc limit exceeded by uid 0, please see tuning(7) and login.conf(5). /kernel: nearing maxproc limit by uid 0, please see tuning(7) and login.conf(5). /kernel: Process with Most Children- 1:init - Children - 211 /kernel: maxproc limit exceeded by uid 0, please see tuning(7) and login.conf(5). /kernel: Process with Most Children- 1:init - Children - 211 /kernel: maxproc limit exceeded by uid 0, please see tuning(7) and login.conf(5). /kernel: Process with Most Children- 1:init - Children - 211 /kernel: maxproc limit exceeded by uid 0, please see tuning(7) and login.conf(5). /kernel: nearing maxproc limit by uid 0, please see tuning(7) and login.conf(5). /kernel: Process with Most Children- 1:init - Children - 211 We have been recommended to change following set interfaces reth1 redundant-ether-options lacp periodic fast to set interfaces reth1 redundant-ether-options lacp periodic slow If someone had similar experience, would appreciate your help.
