DMA failure ?
Our Solaris was hung yesterday, and dmesg show that,

nxge3 : <== nxge_m_start: initialization failed
nxge2 : nxge_dma_mem_alloc:ddi_dma_mem_alloc kmem alloc failed
nxge2 : nxge_alloc_rx_buf_dma: Alloc Failed: dma 9 size_index 10 size requested 4194304

Does it mean the DMA failure ? How do we solve that ? More RAM to the Solaris ?

Many thanks !!

Thanks, I will edit as mentioned, but this line

"Note that a fix for CR 6722278 is needed for the tuning to take effect"

do I have to install that patch to take effect ?

just have a look if there are some actual tuning settings... if yes, take them out and try without the settings... if the above messages still appear, we've to look for other problems.
