The most likely problem is the fact that they are still shipping mid-tier 7.1.00.006 with ar*70.dlls that are almost guaranteed to crash mid-tier (and tomcat with it) if you try to access the CCM Calendar View from any client. I restored the six Feb 2008 versions of the dlls from 7.0.01.006 and the calendar immediately began working correctly. I can't believe (okay, yes I can) that they have not incorporated this file correction into 7.1 mid-tier patches post 002 - they've known about it since February 2008!
At this point the mid-tier patch 006 and flashboards patch 005 appear to be stable, but I still refuse to update production until I see it behave properly over much more testing. Since we are prototyping a lot of Asset and Change configuration and usage on development, we will be pounding on it steadily for the next two weeks.

Its over 24 hours now that we upgraded our production to patch 006 (we have 10 mid tier servers behind a load balancer) and none of the servers have crashed as yet whereas on an average with patch 003 at least 5 of them would have crashed in a day. On one freak day we had 9 of them crash.

Dev was running fine as 7.1.00.002 mod with 7.0.00.006 *70 dlls to work properly with CCMCalendar. Flashboards was fine except for the "normal" errors in the mid-tier log. Tomcat was 5.5.26 per instruction from support last spring, since rescinded. Removed mid-tier and tomcat. Installed mid-tier 7.1.00.006 with bundled tomcat 5.5.25. Upgraded Flashboards to 7.1.00.005 (there is no 006). All of my java is 1.5.0_14 and will remain that way - has been stable for a year with 7.1.00.x code. Flashboards is now crashing in SOME consoles, not others (Change, not Incident or Asset). Was crashing ALL the time until I reinstalled it again... CCMCalendar crashing too, now - had not checked it in a while, though. Lots more testing to do, but it's hardly stable.

I have it running for a few weeks on UAT with no problems, and just yesterday went live on production and no problems so far. It seems to have ceased crashing as regulary as it used to. I am using Tomcat 5.5.25 and java 1.6 (I can get you the exact version if you want that.). And I have my max memory set as reccommended earlier on this thread by me (about 65% of the total available free memory before tomcat is started with every other service besides tomcat started).. Are you on unix or windows? I am on UNIX.

Considering that the production tomcat 5.5.26 under mid-tier 7.1.00.002 has crashed only once in the last nine months (last October), I'm not convinced yet that 006 is any improvement. Am working with support on it...
