Question

Coldfusion 8 scheduler not rescheduling task

Answer 1

+3 A:

not for nothing, but i've never seen anything like this with cf8. are you sure that you have the latest hotfix and jvm installed? this might have been something in cf8 that was fixed in 8.01.

hotfix 2 for cf8.01

list of all hotfixes and updates for cf8.01

hotfix 3 for cf8

list of all hotfixes and updates for cf8

latest jvm

upgrade instruction for jvm

If you suspect that it's an uncaught exception causing the issue, then might I suggest logging portions of the process. Case in point, I had a similar problem with a scheduled task where it would just bottom out for no reason (never had the reschedule problem though). What I ended up doing to diagnose the problem was use cflog to write out portions of the process as they completed. This particular task too about 4 minutes to complete but ran through about 200 portions (it was a mass emailer for a bunch of clients).

I logged the when the portion started and completed along with how log it took. By doing so, i could see what portion would trip up the whole process and knew where to focus my attention.

+1 I had this issue and hotfix solved it for me if I recall correctly

I have CF updated to v. 8,0,1,195765, so I presume that includes this hotfix? Or should I still look at getting this hotfix installed?

unfortunately you can't tell by just looking at the version number. you'll have to look in your coldfusion\lib\updates directory to see if the file chf8010002.jar exists. also make sure your Java Version is 1.6.0_13

also, just wanted to point out that in my answer i only provided the link for the cf8 hotfix and NOT cf8.01 which are DIFFERENT! i updated my answers with link for both as well as the listing for all hotfixes and updates for both versions. remember that cf8 and cf8.01 have different updates and hotfixes and can easily get confusing.

@rip747 - thanks for that clarification. Will try that hot-fix shortly.

Initially it looked like those updates might have worked but, alas the same issues are back. I suspect CF is swallowing an exception as nothing is showing up in any logs. May have to use a different non CF approach which isn't very satisfactory :)

updated my answer with some more ideas.

@rip747 - Thanks for the feedback - I have tried this debug approach and my code finishes every time with no exceptions. When I say there might be a swallowed exception, I'm thinking in the scheduler code itself. This is very frustrating as the problem only seems to occur sometimes. I'll keep thinking about it however.

Answer 2

A:

We have cfusion 8, with Hot fix chf8010002.jar applied and running Java Version 1.6.0_13.

Hourly schedules frequently fail to reschedule themselves. (removing and recreating the schedules seems to "re-initialize" them.

So it doesn't look like the hot fix or java version 1.6.0_13 has resolved this kind of scheduling issue.

Any ideas?
