Hi,
I face with cannot open session too.
I've recorded and then run spider + active scan until it finish first round.
After developer fix vulnerability, i open session aim to re-run. I wait for 3 hrs nothing happen, until ZAP is not response.
- .session file is 190byte
- .session.data is 31GB (i also try to remove .session.data and then open session from ZAP, face with error message "Error opening session file")
What should i do to open it (or reduce size of .session.data) and continue testing.
