survey isn't reachable until all mails sent - by: adishardis

If I send out 1000 mails at a time, limesurvey takes some time to process the request. while the mails are being sent one after another, nobody can access the survey until limesurvey is done sending all the mails and I'm thinking we loose some respondents due to this.

I'm I doing something wrong and is there a way to circumvent this behaviour. I really can't be sending out less than 1000 mails at a time cause it would take to long so that isnt an option.

Cheers!
