| | | Tips needed: restarting tomcat without risk of java.net.BindException | Tips needed: restarting tomcat without risk of java.net.BindException 2006-11-17 - By Bryce Nesbitt
Back
We have a Tomcat application, which binds to port 8080 and AJP 6135. At
3 am we restart this application (because of a memory leak). But
sometimes it is unable to bind to it's own port, and it just dies and
never starts. Naturally this causes unhappiness. The server.xml is:
<Connector port="6135" protocol="AJP/1.3"
enableLookups="false"
connectionTimeout="20000"
maxThreads="150"
minSpareThreads="25"
maxSpareThreads="75"
/>
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
And the Java exception we get is:
INFO: Starting Coyote HTTP/1.1 on http-8080 (See http://ttp-8080.ora-code.com)
Nov 16, 2006 7:08:02 AM org.apache.catalina.startup.Catalina  start

We're using Fedora Core 5 (fc5), and the dtomcat5 startup script. Do we
have to wait at least 20 seconds to be sure the port is clear?
