Re: Unable to stop monit

[Martin Pala]

Please can you provide more details about the system?

There was one report about the same problem when monit is running in LXC 
container: 
https://bitbucket.org/tildeslash/monit/issues/317/monit-stuck-in-uninterruptible-sleep-state

It doesn't seem as monit bug though - the problem seems to be in FUSE driver 
which blocks in the read() system call.
