VMware released the ESXi 5.5 Patch 4 to resolve the NFS connectivity and OpenSSL issues.
Detailed information can be found in the bulletin KB2077360.
The patch fixes the following issues:
- When you run ESXi 5.5 Update 1, the ESXi host intermittently loses connectivity to NFS storage and an All Paths Down (APD) condition to NFS volumes is observed.
- The OpenSSL library is updated to version openssl-1.0.1h to address CVE-2014-0224.
After applying the patch, the ESXi 5.5 build number will be 1881737. The patch is available for download at: http://www.vmware.com/patch/download/.
