Starting server in Weblogic: "I/O error while writing to file The process cannot access the file because it is beign used by another proccess - weblogic

Question

I need help with solving issue with Weblogic. In freshly installed WebLogic 14.1.1 I've created new server and machine for this server. I have working NodeManager launched in CMD, but when I try to start the server (new or one I've configured earlier) I get error from NodeManager that result in FAILED_NON_RESTARTABLE state. What I get from the NodeManager logs, it tries to access this server log file, but it fails with error from title. I've tried to reinstall everything but nothing seems to work.

I've installed Weblogic12c and same problem occurs.

Answer 1

I've accidently found anwser after messing around. Node manager logs are missleading. I thought that problem was with my computer configuration, tried different java versions, different weblogic versions etc. In my case it was port conflict. Port that I configured was already in use.
In weblogic 12, then I later got same error in NM, but now server logs were helpful.
