EE,

I have an issue with vSphere 4.1 U3 (and previous U's) freezing once a week at completely random times and random hosts. It requires a reboot to get any functionality out of it.

I just downloaded the logs from vCenter but don't know which log to look into or how to read them

Any advice? Thanks in advance

/var/log/vkernel.log

but reading logs can be a nightmare, and the fault may not be detailed in the logs. Once you have rebooted the host the logs will be gone.

the best thing is to setup syslog server (VMware has a free one), or use Kiwi Syslog, Splunk, and setup your servers to send their logs to a syslog server.

VMware KB: Enabling syslog on ESXi 3.5 and 4.x

or use vMA and get the logs sent to the vMA.

I would check, datastores are connected correctly, and check the hardware (memory and disks).

Use memtst86+

If you have a support contract with VMware, create a support bundle, and esclate a support request to VMware.
