Hi Team,
I am currently running Mailman 3 with version 3.3.1 and in built postfix version 2.10.1-6 on RHEL 7.5 in production environment from the past 2 months almost.
From the past few days, I found my server is responding to the users very slowly and throwing the Server Error page (of course getting the required page after multiple refreshes) for almost every click on the postorius pages (not yet observed on hyperkitty front end which in fact is not so important for me as of now).
During that time, I observed in the mailman.log an error message saying "Could not locate column in row for column 'user.id'". The complete traceback log is attached with the mail. The error message is generated for almost all the lists and all the clicks.
And despite this error message, I don't know how the required page is loaded after a few refreshes of the webpage.
I don't know how to resolve this issue. Please advise. Also, please letme know if anything I need to share with you.
