[ic] strange error in logs now and then

[DB]

IC 4.8.6 with modified foundation under redhat 7.1. Things seem to be 
working for the most part. Maybe once or twice a day I see something 
like this in my catalog's error log. I didn't see much in the docs or 
archives.... can anyone tell me if this is a problem and if so how to 
solve? Mayeb more RAM... server has 256KB currently.
