crash when trying to upgrade from 2.0.x to 2.3.x

[Aki Tuomi]

squat has been obsoleted since 2.3.0. You should use either solr or lucene (if it works), there is also xapian based flatcurve plugin available for 2.3 from community (will be in core for 2.4).

From your question - am I right supposing that if I will get rid of squat things will improve ? Also seems like it's worth mentioning that downgrading to dovecot 2.3.15 improved things radically - no crash at this time (with the same set of configuration files).
