LDN - Luminis Developer Network

This week our Luminis web server has started having issues. It is running on a Sun T5220 Solaris 10. Luminis version 4.2.2.34. After running for an hour to hour half it becomes unstable and stops responding. Banner channels are unable to be rendered. At the end of the slow response users trying to get logged in get the "too many simultaneous logins" message. By that point the system is gone. Just before it becomes unstable we notice ping packets are lost to the luminis server. No memory errors in log files. No error messages in system logs.
