Cloudron MySQL Rate Limit

  • Hello,
    During importing a very FAT .ical file in NextCloud, I get some SQL error and I would like to check if they came from the rate limit in the IPtable, how can I by-pass or regulate that ?


  • Here a log part :

    I guess this is coming from PostgreSQL since that is what the next cloud app uses. There is no rate limit in IPTables but there is a max_connection setting of 100. Strange that nextcloud is hitting such a high limit but I am guessing it is some bug in the importer.

    There is a suggestion at!category-topic/calendar/calendar-not-loading/EqOUPboHrmU on how to break up iCal file into smaller parts and import them one by one. @saglagla maybe you can try that?

  • @girish I have a 238 ko iCal file.
    I've split it in twice and I went from 250 importation err from 1 err.
    The problem should come from that, thanks!

    I was at the beginning thinking about it (splitting the file) but after that, I was focusing on RateLimit - wrong way! Also, I advise people which want to import a big file to increase drastically the mem allowance of the app (2Gb in my case)
