<div class="jive-rendered-content"><p>Hi,</p><p>I'm getting a WARN message when working with ksession1 even if I'm disposing ksession2.</p><p>Following is the scenario - </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. Create ksession1. Bind HT Handler 1.</p><p>2. Start a process with HT and timer(Timer period 30s)</p><p>3. DO NOT DISPOSE ksession1, neither the HT Handler 1.</p><p>4. Timer continues as expected.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>5. Now, create ksession2. Bind HT Handler 2.</p><p>6. Start a process with HT, no timers in this.</p><p>7. Dispose the HT Handler 2 and ksession2 in transaction using CMTDisposeCommand. Gets disposed successfully.</p><p>8. Timer still continues, but now I get following the WARN message on every timer tick(30s in my case)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>It is evident from the active timer that ksession1 is still active, no issues with that.
