Hi,
We have a strange problem at one of our clients in that Tomcat seems to drop
a specific servlet while running. This happens very sporadically and is
possibly connected with a high load.

In our company we used MySQL and Postgres for several projects. Both
DBMSs are mature and stable, and they are used worldwide for large-scale
projects. Performance-wise we measured some differences, but they were
not so big to notice them in the real-life loads. In other words, having

the only really major difference I can think of is T-SQL stored procedures,
which have no counterpart in Postgres.

choose from 4 languages out of the box and 3 more from addons:

Thank all of you for great help finding it !
