Coldfusion automatically restarted - tracking the cause

Coldfusion is automatically restarting, a lot. It comes in waves, everything seems fine for a while then the server struggles for a few minutes, restarts a lot then settles down again.

I have Fusion Reactor installed, but when CF goes down FR stops logging so it's not really helping. Looking through the archived logs just shows gaps in the logs.

These are all the occourances of the phrase "Coldfusion started" today.

I've been looking at the live server metrics in FR on a second screen all day, the CPU, Memory and requests all seemed fine about 12 midday, then the server rebooted.

Looking at the logs for the hour between 9am and 10am (more than 15 restarts in the hour), the CPU never went over 44% usage and the Memory never exceeded 53% usage - in the recorded stats at least.

There is no JDBC tracking at the moment, so I'll add that to tracking and see if it's MySQL causing a problem, but can anyone help me narrow down the problem, what would cause Cold Fusion to auto restart, and I'm assuming the auto restart is only happening because Fusion Reactor is installed.

It's a Red Hat 5 LAMP stack running Coldfusion 9 and Fusion Reactor 4.5.2

We can at least debug this one. It very likely occurs because you have, in your cookie code, given a cookie a name that is a reserved word. See Jochem van Dieten's article on using reserved names for cookies. So review your code for places where cookies are named.


We had to get some external help to fix this - David Stockton from CFConsultand.com - so I can't really post the solution, but it was a very specific page that only caused a problem if the right URL params were passed in.

It caused a recursive function to be called without exiting.

Is this a new server, upgraded server, changed server?

Just trying to determine if the server restarting is a new thing on this server or if it has been doing this all along (recently built).

It's about 2 years old. It's had updates applied to it, but nothing recently.

CF Version : 9,0,2,282541 

The only major change I've added recently was installing Fusion Reactor, but the problems were already occuring before that.

I have not used Fusion Reactor but since it is a server monitoring tool it seems odd that it is not logging anything.  Before installing Fusion Reactor was ColdFusion restarting or just stopping?  I'm not pointing to Fusion Reactor as the culprit but just thinking that if it is not helping you then perhaps you can disable it until the next ColdFusion failure.  Maybe then you will see something in the logs.  Or can you check previous logs before you installed Fusion Reactor to see what ColdFusion was reporting (if anything).

Just thinking out loud here...


I think Fusion Reactor is triggering the restart - prior to that it would just throw a 500 error which would appear in the browser. The trouble is the user still gets a 500 while the server restarts.

FR doesn't log anytrhing while CF is booting up - it stores logs since the server startup.

I'll try disabling the autorestart, or possibly just FR completly and look at the the cfserver.log

I've still got the problem os something is crashing in my Coldfusion application either way
