The TMOS daemon bcm56xxd may restart due to parity errors.
The bcm56xxd daemon re-initializes the internal switch, which might briefly affect data traffic. The system might report memory parity errors in different tables within bcm56xxd by posting log messages similar to the following: -- info bcm56xxd[8127]: 012c0016:6: unit 0 L2_ENTRY_ONLY entry 120673 parity error. -- info bcm56xxd[8127]: 012c0012:6: Exiting on parity errors. -- notice mcpd[7108]: 01070406:5: Removed publication with publisher id BCM56xxPublisher. The following types of messages may be logged if a parity error is detected by the Broadcom chip in an area that is not used by user data. These type of errors do not trigger a driver restart, and are not user-impacting, however, they can generate a large number of the following types of log entries. F5 recommends rebooting the device to clear this state. -- 012c0016:6: unit 0 FP_TCAM entry 1127 TCAM parity error. -- 012c0016:6: unit 0 SER parity failure without valid count' -- soc_xgs3_mem_dma: EGR_SERVICE_COUNTER_TABLE_X.epipe0 failed(NAK).
Under rare conditions, the bcm56xxd process may restart due to parity errors. This issue affects only the following hardware platforms: -- BIG-IP 6900 (D104) -- BIG-IP 8900 (D106) -- BIG-IP 8950 (D107) -- BIG-IP 11000 (E101) -- BIG-IP 11050 (E102) -- BIG-IP 5000 series (C109) -- BIG-IP 7000 series (D110) -- BIG-IP 10000s/10050s/10200v/10250v (D113) -- BIG-IP 10150v/10350v (D112) -- BIG-IP 12250v (D111) -- VIPRION blade B2100 (A109) -- VIPRION blade B2150 (A113) -- VIPRION blade B2250 (A112) -- VIPRION blade B4100 (A100) -- VIPRION blade B4200 (A107) -- VIPRION blade B4300 (A108) -- VIPRION blade B4340N (A110) Note: The bcm56xxd process is the switch driver daemon for the BIG-IP system.
None.
TMOS has been updated to prevent the daemon bcm56xxd from restarting due to parity errors.
