I get the log as belows:

I can't make sure it's a problem of OOM or a problem of AddressSanitizer.And I can't find where my code alloces a large memory.

This is most likely an OOM. Do you use ulimit -v or something like this?

And I can't find where my code alloces a large memory.

Look at frame #11 in backtrace, most likely you call malloc from here. To get more information, you'll probably want to symbolize the backtrace (e.g. by using asan_symbolize.py script or rebulding your libraries with debug info available).

And I can't find where my code alloces a large memory.

Note that ASan's allocator may mmap N times more than your app requested.

(to proactively allocate memory for future requests)
