Subject Tomcat starts slow
Date Tue, 10 Aug 2010 07:47:25 GMT
Hi!

Tomcat on my ubuntu 8.04 (x64) server starts too slow.

I tried both bundled ubuntu version (tomcat 5.5.25) and newer tomcat
6.0.29.
The start time does not depend on application installed - even empty
tomcat distribution starts slow.

I googled that problem is somehow related to random generator - but I
disabled all SSL - and nothing changed.

The most of the time consumes Catalina initialization. It lasts
more than three minutes. The following lines from catalina.out log near
time gap (turned on finest log level)

[catalina.out]
....

Sending QUIT to java does not produces dump of hanging thread - even
after that soft 'killing' - tomcat continue to start.
