503: Spool Over Quota. Message VPN limit exceeded

mr_goyal Member Posts: 1

I am using spark to publish data to solace topic. What could be the problem for this. In below question , I found out that size of record may be the cause. However, record size is much smaller than the quota we were provided.

Can anyone help me on this?

    Hi @mr_goyal ,
    Looks like you have some Queues that have matching subscription to that topic and one or more of those queues is reaching its spool limit.
    If you have access to the Web manager, you can check the queues from the Queues menu on the left and check if any of those are full and check its subscription. Some of the queues might be subscribing to a very broad topic.

    Remember that when creating a new Message VPN, the default spool size/limit is 0 MB. So even if your queues are 1GB or whatever, the Message VPN must also be big enough for your queues. Check the Message VPN settings, and increase the max spool limit there as well.
