In rare occurrences, BIG-IP hardware is susceptible to parity errors due to unknown source. This bug mitigates parity errors that occur in the SOURCE_VP table of the switch hardware, indicated with the following message in the ltm log: Sep 15 12:12:12 info bcm56xxd[8066]: 012c0016:6: _soc_xgs3_mem_dma: SOURCE_VP.ipipe0 failed(NAK)
This impacts several series of BIG-IP products with hardware parity error mitigation capabilities.
This occurs only on the BIG-IP 10000s/10200v/10250v platforms, and on the VIPRION B4300/B4340N and B2250 blades. The exact trigger of the parity error is unknown at this time.
Rebooting BIG-IP hardware should clear issues caused by hardware parity errors.
A hardware parity error issue has been fixed.
