Timer log entry, timer already exists with this identification?

Setup, Configuration and Use Scripts & Rules

Hi everyone. Need help with this log entry.
Rule will be used every hour, if item values changed. Last weeks, it runs perfekt. Today at 07:36 too. And than this:

2018-08-08 08:36:24.800 [ERROR] [model.script.actions.ScriptExecution] - Failed to schedule code for execution.
org.quartz.ObjectAlreadyExistsException: Unable to store Job : 'DEFAULT.2018-08-08T08:36:25.798+02:00: Proxy for org.eclipse.xtext.xbase.lib.Procedures$Procedure0: [ |$
  val sb
  <XMemberFeatureCallImplCustom>.forEach(<XClosureImplCustom>)
  <XFeatureCallImplCustom>.postUpdate(<XMemberFeatureCallImplCustom>)
  logInfo(<XStringLiteralImpl>,<XMemberFeatureCallImplCustom>)
  org.eclipse.xtext.xbase.impl.XIfExpressionImpl@12fb953a
  <null>.Tanken_timer = <XNullLiteralImplCustom>
} ]', because one already exists with this identification.

Post the code please.

var Number lastgGasStations = 0
var String lastCheapestGasStation = ""
var Timer Tanken_timer = null

rule "My cheapest gas station"

when 
 Item gGasStations received update
then
    if (Tanken_timer === null) {
        Tanken_timer = createTimer(now.plusSeconds(1), [ |
    
        val StringBuilder sb = new StringBuilder
        gGasStations.members.filter[ i | i.state == gGasStations.state].forEach[i | sb.append(", " + i.name) ]
        CheapestGasStation.postUpdate(sb.substring(2))
        logInfo("***", String::format("%s %.3f Euro", CheapestGasStation.state, (gGasStations.state as DecimalType).floatValue))

Do you still have this problem? I also ran into this issue quite some times already and do not have an explanation yet. I see the issue occurring randomly and it is not reproducible. This used to work without any problems.
I have recently upgraded OH2 a couple of times using different snapshot versions. Right now running build 1369. I do not know yet when the issue actually started though…

If you have figured out what is causing this our how to solve it, I would appreciate if you let me know :wink:

Cheers,
Matt
