Webservices - Couldn't create session - UNAVAILABLE

[MartynasBalaisi]

My process is started, despite WSDL returned an error. How can I know, via WSDL, that process was or wasn't invoked? Detailed explanation of this problem: * The process used in test is very simple: Start -> launch IE with specific website -> Enter data in search field & click search -> sleep 5s -> close browser -> End * Process always outputs False (hardcoded in, not related to issue) * Process is invoked via WSDL (exposed process), using two resource PCs (http://[Resource_PC1]:81**/ws/ProcessName & http://[Resource_PC2]:81**/ws/ProcessName ) If I invoke 6 processes in a couple of seconds (3 per single resource PC) I get these SOAP responses: Resource_PC1: * 1st process: Proper output ("Applicationfound xsi:type="xs:boolean" xmlns="">false") * 2nd process: Fails ("Couldn't create session - The requested operation is not permitted, because the license currently in use does not permit it.......") * 3rd process: Fails ("Couldn't create session - The requested operation is not permitted, because the license currently in use does not permit it.......") Resource_PC2: * 1st process: Proper output ("Applicationfound xsi:type="xs:boolean" xmlns="">false") * 2nd process: Fails ("Couldn't create session - UNAVAILABLE") * 3rd process: Fails ("Couldn't create session - The requested operation is not permitted, because the license currently in use does not permit it.......") Sometimes I get 2 successful outputs on single machine, but in general it looks similar to this. PROBLEM: I can see screens of both PCs - browser was launched 4 times (2x on each machine). Session manager also shows 4 new, completed, records (see screenshot). QUESTION: How can I know with 100% certainty, that process was invoked or not? Why, despite error was returned, process still ran? P.S. This error does not occur if some timeouts are added (e.g.: "Start -> sleep 30s -> launch IE with specific website -> Enter data in search field & click search -> sleep 120s -> close browser -> End"), but this definitely is not a solution. P.P.S. BP version: 5.0.21 P.P.S. Object, which launches browser or performs search, run mode is set to €žBackground€œ. Process is published.

Looks like your license is limiting the number of processes. Check whether you can manually start the same number of processes via Control Room.

I do understand what error means and this is completely OK - problem is that despite the error returned process was still launched. Lets look at Resource_PC1: 1 success and 2 errors returned, BUT in reality 2 processes were started and only 1 did not. I mean - if query returns an error, that process failed, it MUST stay this way:) Why it's being started?

check ""Number of concurrent sessions which may be run "". If the number is more than or equal to 3, Check the mode in launch action.

Yes, number of concurrent sessions is higher, but same server is running 2~3 other processes constantly. Main question is not regarding session count, but process, which was started, regarding WSDL reported error. What do you mean by ""mode in launch action""? All objects, used in this process, has ""Run mode: Background
