Hi
I see this problem for more time, but didn't yet find time to report.
Monit segfaults for me just after startup. Here is end of strace:

When I remove state file, it starts and seem to work fine (it didn't yet
run too long, but looks good enough so far). So there must be something
wrong with state saving/parsing. It fails whenever there is some state
file. I'm attaching one as example.
