/var runs full on VMware ESXi 6.7 on HP Gen8 Server

Today two of my ESXi 6.7 servers running on HP DL360p Gen8 didn’t behave as expected. VMotion and remote consoles quit with internal error.

In vspere syslog I found:

The ramdisk 'var' is full. As a result, the file /var/log/EMU/mili/mili2d.log could not be written.

On ESXi vdf -h revealed a full file system. The milid2.log was the problem and dumped the following errors:

CRITICAL:backend_init:OneConnect Adapter Not Found.
ERROR:rename all the configuration files!
ERROR:MILI_enumerate_elxiscsi:Failed to initialize User Init with status = 19
ERROR:MILI_enumerate_elx_nics:Failed to initialize USer Init with status = 19
ERROR:could not open device node /vmfs/devices/char/vmkdriver/be_esx_nic

In both servers no emulex hardware was installed.  So I removed 3 packages form those ESXis with a reboot between each. The last one solved the problem!

esxcli software vib remove --vibname elxnet

esxcli software vib remove --vibname elxiscsi

esxcli software vib remove --vibname elx-esx-libelxima.so

On my DL360 Gen9 this problem did not occur.
