Symptoms

When attempting to browse a Virtual Machine for File Level Restore, it will hang at "Retrieving contents of backup".  On the VM Proxy a coredump is created for the MountPoint and VmwareFlrWsSvc processes.   We have seen this behavior on 19.4.100-124_HF337047 proxies. 

The journal may show a segmentation fault for the MountPoint process.

Example

avamar_proxy:/usr/local/avamarclient/bin/MountPoint # journalctl -r | grep segfault
Feb 17 16:17:24 avamar_proxy kernel: MountPoint[2550]: segfault at 746c8d ip 00007f3f1079d06d sp 00007ffd58574bb0 error 4 in libvixDiskLib.so.7.0.3[7f3f106c1000+185000]
