There were 10 failed launches in a row, each lasting less than
300 seconds. Giving up. There may be a configuration problem:
please check the logs. <-- Wrapper Stopped
On the Weblogin-page I got the message about a not fully
started background problem.
Any suggestions are welcome
This looks like a bug in Java 6. A similar bug was reported last
week:
https://jira.djigzo.com/browse/GATEWAY-101
For now the best solution is to upgrade to Java 6. See bug
report #GATEWAY-101 for more information.
A possible workaround is to add the following line to the file
djigzo.wrapper.conf
wrapper.debug=true
Let me know whether this work around works for you. It looks like
some interaction between Java wrapper (which starts the Java
process) and Java 6 update.
I will investigate this further.
As a workaround (instead of installing Java 7), you can add
wrapper.disable_console_input=FALSE to the Java wrapper config. You
can add this option by editing the file /etc/init.d/djigzo
Change
WRAPPER_OPTS="wrapper.daemonize=TRUE"
To:
WRAPPER_OPTS="wrapper.daemonize=TRUE
wrapper.disable_console_input=FALSE"
I'll contact the java wrapper developers. It might be some
interaction bug between changes in Java 6 and java wrapper.
Hi Martin,
thank you very much for your fast support. Mailencrypt and decrypt
works fine with the last workaround. But we are running in a new
problem with the weblogin. I always get an ssl-error
(ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION -> Chrome) messages in FF
and Chrome when I try to open the login page.
It looks like Chrome, FF (and Java 6?) removed support for certain
ciphers. In the latest release of CipherMail (3.0.5) the list of
supported ciphers was optimized for security reasons (check with
ssllabs). However Java 6 does not support all those ciphers. The best
for now is to remove the ciphers lists setting from
/etc/tomcat6/server.xml. This way Tomcat will provide support for all
ciphers Java 6 supports. After changing server.xml, restart tomcat
(service tomcat6 restart)
Kind regards,
Martijn Brinkers
