Runtime Error when running Solidworks

One of my users is experiencing a message every hour or so when running Solidworks. 

The message is

Program C:\Windows\sysWow64\SearchProtocolHost.exe

R6016

- not enough space for thread data

Has anyone seen this before?  I haven't had a chance to dig into it at all.  The user just clicks ok and everything seems to continue fine.
