<ul></ul><p>I can't reproduce this.<br />In Kepler-1.0.0 on a multicore Windows 2003 Server with Java 1.6.0_07, I did:<br />1) Started Kepler by clicking in the icon<br />2) Help -> About -> Documentation<br />3) Clicked on "background information about Ptolemy" -> Quick Tour -> "complete list of demos" -> SDF -> DFTSubset<br />4) I ran the demo several times and did not hang for me.</p>
<p>There could easily be a bug here, but I'm not sure what model<br />was being run and on what platform and with what version of the JVM.</p>
<p>To check the JVM version, start up Kepler and click on Tools -> Check System<br />Settings.</p> Kepler - Bug #3693: MultiInstanceComposite actor deadlocks sometimeshttps://projects.ecoinformatics.org/ecoinfo/issues/3693?journal_id=125562008-12-04T23:33:31Zjianwu jianwujianwu@sdsc.edu
<ul></ul><p>The deadlocks appear to occur when using PN (probably due to multi-threading). I'll upload a simple workflow. Note that you may need to try many times to see the deadlock.</p> Kepler - Bug #3693: MultiInstanceComposite actor deadlocks sometimeshttps://projects.ecoinformatics.org/ecoinfo/issues/3693?journal_id=125582008-12-05T19:12:23ZDaniel Crawldanielcrawl@gmail.com
<ul></ul><p>I was able to reproduce the deadlock in Jianwu's workflow on:</p>
<p>Windows XP, java 1.6.0_11, Kepler 1.0.0<br />Mac, java 1.5.0_16, both Kepler 1.0.0 and head</p> Kepler - Bug #3693: MultiInstanceComposite actor deadlocks sometimeshttps://projects.ecoinformatics.org/ecoinfo/issues/3693?journal_id=125592013-03-27T21:24:15ZRedmine Admin
