I'm running into a problem with the APR connector not shutting down
properly. Tomcat runs fine and there are no errors on shutdown, but if
I shut Tomcat down and start it up again I get a socket bind failed
error in the catalina log (attached). I have to wait for several
minutes between shutdown and startup for Tomcat to be able to startup
correctly. If I run Tomcat without the APR connector, I don't have this
issue. This does not occur on Windows, but does on Solaris and AIX.
Has anyone else seen this?
One thing I noticed is that the first thing logged on shutdown is an
"AjpAprProtocol pause" entry, but there is no shutdown, stop or destroy.
Is there any chance the APR connector is just getting paused and nothing
is actually stopping it?
Any help would be greatly appreciated. Thanks in advance.
I suppose you have:
<Listener className="org.apache.catalina.core.AprLifecycleListener" />
in your server.xml
But of course it doesn't guarantee it will be executed in all cases,
if the JVM crashes for example.
On Solaris it can take up to 4 minutes until the OS recycles the
zombie socket.
You can use:
ndd -set /dev/tcp tcp_time_wait_interval 60000
To lower that value.
APR does not try to fool the OS like JVM, but rather behaves like
Apache httpd.
