What was going on when it hung? Were you running Groovy script?
I've noticed that if I run test cases and leave the Request/Response window open, it usually hangs. I then have to kill SoapUI thru Task Manager and restart it. I've lost any changes, so I've learned to Save All before running and hopefully I remember to close the Request/Response window. This occurs on Open Source versions 4.5.0 and 5.5.0. My script is for data driven testing and it loops, but it will hang either immediately or after 1 loop.
You can see a video of this, which just happened to me earlier this week, on YouTube http://youtu.be/zxlp_vViOHw?hd=1
So far I don't see any solutions. it's happened to me many times. I have tried many options but so far no proper solutions. ( the below I have used so far )
Solutions 1: Increased memory size to 1GB
parameter : -Xms1024m
locations : C:\Program Files\SmartBear\SoapUI-5.3.0\bin\SoapUI-5.4.0.vmoptions"
Solutions 2: Enabled Autosave after 20 mins and before Autosave create a backup file ( atlist backup copy is not corrupted)
Solutions 3: Disabled autoSave options. and start using Save when I wanted to save
Solutions 4: Disabled and closed unused project in your current workspace.
Solutions 5: If you are running big load ( data-driven test ) where many loops are running, run this project with testRunner batch mode
Solutions 6: If your testSuite is running and you are doing any test Parallel please stop doing this. Many times it got hanged while sending request/response.
with combinations of 3,4,5, I found you will never have faced any issue. but I make mistake and soapUi hanged and Project filled with null null null ( which can't be reverted back )
