It's looping somewhere forever. It would be useful to know where. Could you try upgrading again and when it gets back to looping forever, show the results of:
strace -tt -p pidof lmtp
Does it print anything? If it does, show the first 20 lines or something.
Also, and probably more importantly:
gdb -p pidof lmtp
bt full
Unfortunately your binaries are probably stripped so it probably shows only function names, but that's better than nothing.
Could there be a regression from the LMTP fixes introduced in 2.0.2?
There is only a single LMTP related change in v2.0.2, and I doubt that's the cause: http://hg.dovecot.org/dovecot-2.0/rev/7fef89fea00e
