Could not create lockfile /tmp/.postman.lock

  • In my SMTP email log I’m seeing sporadic messages that read “Could not create lockfile /tmp/.postman.lock” and the associated emails are not being sent. I *do* get an email notification that reads:

    You getting this message because an error detected while delivered your email.
    You are welcome to post a support issue.
    The log to paste with your support issue:
    Could not create lockfile /tmp/.postman.lock

    … but no other explanation.
    What is causing this error and what can I do to eliminate it?

  • The /tmp folder is outside the web folder root.
    I think it’s a permission error need to be solved by your web hosting.

    I would have thought that if it was a permissions issue it would have occurred everytime this email was triggered, however, the offending email the other day was from a nightly backup which ran and generated the email just fine this morning.

    I’ll check with my ISP to see if they have any logs, but it sure seems odd that it would have been directly a permissions error at the OS level.

    You are correct that the /tmp folder is outside the web folder root.

    Please paste the diagnostic test output here.

    The hosting provider reports that the permissions on the /tmp folder (and I’ve confirmed) is 755. This should allow the ability to create files in that directory, unless you are using a different id (and of course, the “why only sometimes” question still holds true).
