We're running ColdFusion 7.02 on a Windows 2003 production server(IIS 6) that appears to have a memory leak or coding issues or both. The jrun.exe will run up to 1.2 gig of usage and higher in task manager. Somewhere above 900mg of usage the CF processes will lock up causing us to have to stop jrun and let it restart or in some cases, reboot the server. Obviously, this plays havoc with our CF applications and pages. In addition, we have also located what appears to be coding errors in the CF application logs. some examples are, 'dividing by zero', 'items undefined', 'access page timers being exceeded'. As we are not CF programmers on our side of the issue we don't always know what effect these errors have on the processes on the server. The logs have been forwarded to our application support/programming section and it appears some corrections have been made and are continuing to be made. On Monday,7/18, we were required to restart jrun approx 14 times throughout the day and evening on this server. This slowed through the rest of the week up to this point with some specific times when it had to be restarted at approx 3-4 hundred meg, instead of 900mg to 1.2 gig. Update: many coding errors have been repaired over the last week and the high number of restarts has dropped but still present. On the ColdFusion side we have applied a hotfix 65335 which is suggested to work with the way jrun releases memory with file uploads. This didn't appear to make any difference when applied but we suspect there is a problem with the path it was applied to. We are correcting that today. I have also looked at one of the CF updater files to try but in the past applying one of these may have fixed one error but created others. We are looking at the JVM version because I have seen in some of the blogs where there are a couple of less beneficial versions and an upgrade can help. we're at 1.4.2_09 but I've read where _13 or _19 would be better. We are in the process of testing applications in the CF 8.0 region that is setup (and making it a priority)but this won't happen overnight. May take several weeks. Please, anyone who has seen similar errors with jrun in a 7.02 environment, can you offer some quick fix solutions, or even not-so-quick? Thanks v
