Log spew

We have updated driver & firmware for the Broadcom 10Gb NICS

Since then we have seen the following log spew on the host:

Anyone experience similar or know if this is a concern?

Hi,

we have experienced weird problems with upload (stalled) on some heavy network utilized vms. ESXi hosts were HPs blades with driver 2.712.70.v55.3 (fw 7.13.23), what is recommended version in HP recipe (https://vibsdepot.hpe.com/hpq/recipes/HPE-VMware-Recipe.pdf)

esxi logs with version 2.712.70.v55.3 are full of

2016-06-27T16:28:23.868Z cpu14:32868)<3>[bnx2x_esx_init_rx_ring:1946(vmnic0)]disabling TPA for queue[1]

2016-06-27T16:28:23.890Z cpu14:32868)<3>[bnx2x_dynamic_alloc_rx_queue_single:789(vmnic0)]Could not start queue:1

2016-06-27T16:28:28.866Z cpu0:32868)<3>[bnx2x_alloc_rx_sge:734(vmnic0)]Can't alloc sge

We are testing this never version 2.713.10.v55.4 and it seems promising. I'm planing opening support case with vmware and hp.

I have found  Slow backup performance

mentioning this errors related to slow performance.

Have a look at this.

This is a driver issue.

Hello all,

after year we are experiencing similar behavior after updates. ESXi is 6.5 Update 1 (6.5.0 #1 SMP Release build-5969303 Jul  6 2017) with latest HP driver

   Driver Info:

         Bus Info: 0000:04:00.1

         Driver: bnx2x

         Firmware Version: bc 7.13.75

         Version: 2.713.30.v60.7

I have found that newer driver should exist, but download is not available at Download VMware vSphere

I also have found blog post which mentions some bricked network adapters with this driver http://www.thevirtualist.org/bricked-qlogic-broadcom-bcm57840-driver-update/

http://www.thevirtualist.org/bricked-qlogic-broadcom-bcm57840-driver-update/

Maybe that is reason for call out?

Anyone experiencing same bahavior again?

Please see this link for the newer driver - https://my.vmware.com/group/vmware/details?downloadGroup=DT-ESX60-QLOGIC-BNX2X-271330V608&productId=...

I have the same issue on Broadcom cards in my hosts with this in the logs and it is actually causing APD in my iSCSI adapters.  I am going to try the newer driver to see what happens as we have the latest firmware - 7.14.37.

Hi,

Thank you for link for the driver, finally I have release notes. I have found driver itself before in dell iso image and extracted it, but without change log.

We can see there

2. Problem: CQ93244: VM traffic stops after error recovery.

    Change:Invoke stop_queue() before disable TPA, to aviod memory leak.

           Free Rx filter table during Recovery unload, to avoid memory leak.

    Introduced: 2.713.30.v[50,55,60].1

We can see in logs that memleak before first bnx2x_esx_init_rx_ring error:

2017-09-19T21:18:34.615Z cpu3:65645)vmklinux: alloc_pages:1010: This message has repeated 1 times: gfp_mask=0xd0, order=0x0, vmk_PktSlabAllocPage returned 'Out of memory'

It seems HPE image iso and HPE drivers relase contains this problematic driver. DELL have newer - fixed driver.
