We're experiencing a problem on both production and test systems that has
only started to occur in the last few weeks (no new version of any software
have been put live to anyone's knowledge) that has us quite stumped.

Intriguing.
For a complement of information :
- what is the exact platform ?
- is Tomcat started via jsvc ?
- as a matter of fact, *how* is the main Tomcat being started ?

Unfortunately Solaris' netstat doesn't know a option to show listeners.

This is on Solaris 10 which doesn't have that issue. Each process is
allocating its own storage so it looks like it's completely separate from
the parent process, threads would share the parents storage space.
No, we definitely aren't starting any additional processes ourselves.

I'll get that checked when it next happens (it's doing it daily at the
moment sometime several times).
We've already tried to match the events with the activity on the parent JVM,

I think all the vhosts need webapps as the appbase for Railo, as this
is how it is on all my other installs as well.
here is the exact error if it helps.

Ok, fishing in the dark really, but trying to accumulate more clues.
What about the other questions (how is Tomcat started) ?

We have a problem with tomcat server. For hours, cpu usage for tomcat7.exe

Any idea about this?

definitely a thread dump is required (see jstack.exe).
a) in case one CPU core is running at 100% and all others are
considerably more or less idle it might be a garbage collection issue,
too (enable GC logging or attach from JConsole to your process)

The tomcat service is managed by the Solaris service management system (I

Tomcat's JDBC-based session store serializes session objects in order
