I'm going to assume that there is a memory leak . How do I address this or track down the origins?

Please not that I do not make any explicit calls to sqlite using sqlite commands. However, I do make ample use of html5 localStorage and I have external JS libraries that make use of storage using cookies.

Answer

The stack trace shows you the path that the code follows during the execution of your application. It can help you to find were did the error took place.

Looks like the error is related with sqlite3 in your stack trace. Each line inyour stak trace is a function in the code:

sqlite3MemRoundup
sqlite3MemMalloc
mallocWithAlarm
sqlite3Malloc
sqlite3DbMallocRaw
sqlite3VdbeMemGrow
sqlite3VdbeExec
sqlite3_step

You should investigate the parts of your application that use sqlite.

I don't think it is a JavaScript memory leak but you can use the Chrome memory Profiler to study the memory usage and find leaks https://developer.chrome.com/devtools/docs/javascript-memory-profiling
