1.6.1.6 is pretty old, and you should, at a minimum, upgrade to the latest
1.6.1 release, which is 1.6.1.20.  There are a myriad of bugs that have been
corrected in that time.  That said, the 1.6.1 branch is in security mode.
Even if you found a legitimate bug, it is not going to be fixed in branch, and
there will be no more releases of the 1.6.1 branch, other than for security
fixes.

The exact error that you're looking at is a memory management issue.  A
dynamic buffer, which started as size 512, needed to be expanded, but the
memory allocation failed in some way, and this warning message was the
result.
