There seems to be a lot of people experiencing lockups when switching to
GlassFish.
Are you using the Microsoft JDBC driver? 1.0, 1.1 or 1.2? We were
using 1.0 and the loginTimeout had no effect. We've switched to jTDS,
an open source MS SQL Server driver and set a loginTimeout on it. We've
been running stable for a week now. We've been stable for over a week
before, so I'm not jumping to conclusions yet.
Thanks,
Ryan

Setting this however did start to throw up exceptions in the server log on startup. Probably because certain aspects of glassfish is only supported by grizzly (or so I have read).
