Hi,<br />
<br />
i had some issues like that on Sun and HP blades. After opening support cases with VMware, Sun and HP we have found out that the driver for the RAID cards were causing this issue on Sun (VMware made the patch) and on HP it was resolved with firmware upgrade of each component (servers and switches).<br />
<br />
This problem was causing the ESX/ESXi server to stop responding to network requests, no I/O to storage infrastructure and the only way to make the server responsive was to power cycle the host.<br />

I have a ESX blade in a HP enclosure. &nbsp;It stopeed talking to VCenter to the point I could only access it from the physical console.<br />
<br />
i rebooted the ESX blade &amp;&nbsp;it took about 25 minutes to shutdown, it came back up quick.<br />
<br />
Any tips on finding the root cause?<br />
<br />
Looking at /var/log/messages I see a lot of:<br />
<br />
syslogd 1.4.1: restart.<br />
<br />
once an hour up until i rebooted, then they stopped.

ESX server hang/crash

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
