On windows it leaves an errant uvapi_slave process that you have to kill manually. It doesn't go away on its own from my experience. Debugs in programs do the same thing.
I usually find them because they consume a license. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Symeon Breen Sent: Monday, August 08, 2011 3:20 PM To: 'U2 Users List' Subject: Re: [U2] uniobjects question It isn't possible, the api_slave process will crash, probably leaving an screwed uvcs process, licencing will take a while to catch up so you will be using licences, if you are using pools, then it may cause problems up at the webserver level, and you can get in a right old mess. It is just the same with a phantom, as soon as it sees an input and there is no buffer, it dies. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Doug Chanco Sent: 08 August 2011 14:57 To: U2 Users List Subject: Re: [U2] uniobjects question I totally agree with your response but what me and the java developer are discussing is if it's even possible (I say nay) I will write a java program to test but I was hoping with the vast sea of knowledge on this group that someone would know, if it was possible or not Yes it should never be done and yes your standards are spot on.
