Try to apply latest ESXi 5.5 patches (5.5.0c) for resolving issue.
I suggest you to contact VMware support.
Yes, it is better to upgrade to latest patch for some critical security issues i.e heartbleed.
we are having the same problems with ESXi 5.5.0 U2 and SVC.
The error messages are the same as in your log:

Did you solve your issue?
Please conduct a test to see if its the storage or the ESXi, try using the same esxi version in lab with software based storage such as openfiler and test it, if it still crashes, apply the patch if not, you know the problem then!
