I'm assuming ifModifiedSince is already a multiple of 1000 (these are
times in msec). In that case, the following comparison would do the
same thing:
if (ifModifiedSince (lastModified - 999))
or
if (ifModifiedSince = (lastModified - 1000))
But I suppose that /1000*1000 might be

I appreciate you addressing this issue. But isn't this fix just
delaying the problem? An IEEE double has 52 bits of mantissa versus
32 bits for size_t. So the problem will now occur at 4 PB
(petabytes). Sure, that's a lot of bytes and my webservers would

What's not obvious from this static snapshot is that the middle

I suggest that maybe doubles would be better for the read/write
bytes. Although I still prefer a model that doesn't break at
rollover (reset all counters or moving averages for example).

I've been getting this behavior on exactly one of our several web

issue (RAM?). It always occurs within the jvm (jvm.dll in your case)

Patching Tomcat 4.1.30 is pretty much what I have done. I spent a lot
of effort getting our installation working in a stable way. And a lot
of that effort was in applying patches similar to the ones that are in
the baseline but have never been released.
As far as moving to Tomcat 5.x, I

There have been some important bug fixes in the baseline since April
that haven't made it to a release version yet. Are there plans to
release another version of Tomcat 4.1?
The changes I am interested in some fixes that were done by Glenn and
Markt but some thought they might be too risky.
I'm just a list lurker (so my opinion doesn't count) but I'm really
happy to see these fixes. I have had to override JDBCStore and
PersistentManagerBase at my site to make similar fixes so that things
work acceptably (yes, I submitted patches but they weren't accepted).

. The JDBCStore is documented in
/webapps/tomcat-docs/config/manager.xml .
And those docs are up to date.
Perhaps this file should be removed from CVS.

It would be nice if Tomcat detected the encoding. I posted a similar

Here's how I think you should handle this.

I wrote a patch to JDBCStore.java that adds a new column to the
tomcat$sessions table to hold information about the webapp that is
trying to save the session.
The need for this comes when you run multiple webapps which each may
have classes in session that are unique to the webapp. As
I just discovered another feature of the the JDBCStore.
If your webapps save their own classes in the Session (as webapps are
wont to do), then when JDBCStore runs its checks to clean the database,
it will try to pull in ALL sessions including those from other webapps.

I've been noticing that sessions are backed up over and over until they
are swapped out, even if they haven't been accessed since the first
backup. This could put a pretty heavy burden on the database (or
file) store, especially if the checkInterval is low.

I'm not quite sure why it does but I am finding the implementation of
this class in particular to be somewhat flawed. For example, the
recycle() method doesn't remove a session from memory (via the Manager)
but expire() does. So, when something is recycled, it is actually
left on the list
As currently written, JDBCStore pulls session IDs from the database
using a query of the form:
SELECT COUNT(s.id), c.id FROM tomcat_sessions s, tomcat_sessions c
GROUP BY c.id;
While this query is a clever way to get the count back as part of the
query, it does not scale well to larger
