I have a HTTP server app, and after some running, I can see a huge (1.2 GB) virtual memory usage, but the physical memory usage is at a normal level (10 MB).
The output of ps command:
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME
www-data 2769421  0.0  0.4 1210720 10156 ?       Ssl   2021  22:10
The output of the free command seems to be OK:
              total        used        free      shared  buff/cache   available
Mem:        2035160      292508      292132       55176     1450520     1499604
Swap:       1048572        6500     1042072
Is that normal, or I have some memory leak?
What can be the cause of it?

It can be leak, it can be fragmentation.

I suggest dumping MemoryProfile from time to time to find out.

Does it grow from 1.2G further? What is "some running"? Hours, days, weeks, how many requests?
