I have an application running under Wildfly 9.0 which sends emails with attachments.
Some of these emails can have large attachments, when this happens I get an error message "552 5.2.3 Message size is over limit (15728640).
How can I increase Wildfly's maximum limit so that it can send larger attachments (e.g. 20mb)?
What parameters should I change on?
Thanks
Needs to increment the value of Max header size and Max post size of the server.
From wildly console : Configuration:Subsystems > Subsystem:Undertow > Settings:HTTP
Select the HTTPListener anche change the value of the attributes

Our project has Microsoft Service Bus (on-prem ) running on Windows 2012 R2 servers for message processing.
When sending messages to service bus topic above the size limit (say 10 mb ) , services bus shows processing error – throws socket timeout exception.
Just wanted to know ,
if anyone has worked with sending messages (say > 10 MBs ) to Service Bus Topics . Would appreciate any suggested approach on how to handle this.
Also is there a way to increase the service bus timeout configuration or message size limit settings on Service Bus Topics either through Powershell cmds or Service Bus Explorer.
Service Bus queues support a maximum message size of 256 Kb (the header, which includes the standard and custom application properties, can have a maximum size of 64 Kb).
There is no limit on the number of messages held in a queue but there is a cap on the total size of the messages held by a queue. This queue size is defined at creation time, with an upper limit of 5 GB.
Are you asking about sending a message which is of size 10 MB? Service Bus doesn't allow that large message. For Premium, the maximum message size is 1 MB, and for Standard, it's 256 KB as #Ana said.
Also is there a way to increase the service bus timeout configuration
or message size limit settings?
Yes, there is a possibility to handle time-to-live property of messages which can be configured either at the time of Queue/Subscription creation or while sending Individual message. Refer to set Time to live for Queue as well as message.
Also is there a way to increase message size limit settings?
No, as the maximum size is 1 MB (May be increased by Azure in the future).
To answer this "Can we Send messages (say > 10 MBs ) to Service Bus Topics".
Now as of today, the updated answer will be YES: The Premium tier of Service Bus, enabling Message size up to 100 MB. Where as Standard is up to 256 KB as of today.
How to enabling large messages support for an existing queue (or topic)
Recommended:
While 100 MB message payloads are supported, it's recommended to keep the message payloads as small as possible to ensure reliable performance from the Service Bus namespace.
The Premium tier is recommended for production scenarios.
We would like to reject the messages being placed in hornetq greater than 50 MB.
Could we restrict it in the configuration at queue/connection factory level.
Placing large messages in HornetQ is causing heap issue and the server is getting crashed.
Any help appreciated.
Edit your .xml configuration like:
<address-setting match="your/queue/address">
<max-size-bytes>104857600</max-size-bytes>
<page-size-bytes>104857600</page-size-bytes>
<address-full-policy>DROP</address-full-policy>
</address-setting>
From the docs:
Messages are stored per address on the file system.
Instead of paging messages when the max size is reached, an address can also be configured to just drop messages when the address is full.
..to do so, set address-full-policy to DROP (messages will be silently dropped).
The above settings are documented at:
https://docs.jboss.org/hornetq/2.2.5.Final/user-manual/en/html/queue-attributes.html
While, especially concerning the message size elements: https://docs.jboss.org/hornetq/2.2.5.Final/user-manual/en/html/paging.html
I am using Red Hat JBoss AMQ 7.1.0.GA and testing flow control with producerWindowSize, I used example under amq71Install\examples\features\standard\queue, here is sample jndi.proerties:
# Neither of the following parameter works
#connectionFactory.ConnectionFactory=tcp://192.168.56.11:61616?producerWindowSize=1024
java.naming.provider.url=tcp://192.168.56.11:61616?producerWindowSize=1024
I send 10 messages with total size smaller than 1024 but still can see them arrived on broker, did I miss something or I misunderstood this parameter?
Best regards
Lan
Yes, I believe you've misunderstood this parameter.
The "producerWindowSize" is the number of credits which the client will request from the broker. Each credit corresponds to a byte of data. When the client receives those credits then it will be able to send that number of bytes. In your case the client requests 1024 credits from the broker which it receives, therefore it is able to send 1024 bytes before requesting more credits.
Since you're sending 10 messages with a total size smaller than 1024 then you should expect them to arrive on the broker without any issue.
Sometimes my RPI drops internet connection and cron jobs starts failing left and right and the queue grows incredibly fast, and once I reconnect it just floods me with email.
I'd like to limit the mail queue to a fixed number, is this possible?
Yes, You can limit the maximal number of recipients and active queue size,
In main.cf please add these config options
qmgr_message_active_limit = 40000
qmgr_message_recipient_limit = 40000
Refer this links for better understanding active limit, recipient limit
What you want is not really possible.
I'd say a solution would be to either limit the size of the queue (by using the queue_minfree parameter) or make the system more robust regarding internet outages (like not sending mails for every error cron produces).
Does this value only affect incoming traffic? If i set this value to say 4MB on zookeeper server as well as zookeeper client and I start my client, will I still get data > 4MB when I do a request for a path /abc/asyncMultiMap/subs. If /subs has data greater than 4MB is the server going to break it up in chunks <= 4MB and send it in pieces to the client?
I am using zookeeper 3.4.6 on both client (via vertx-zookeeper) and server. I see errors on clients where it complains that packet length is greater than 4MB.
java.io.IOException: Packet len4194374 is out of range!
at org.apache.zookeeper.ClientCnxnSocket.readLength(ClientCnxnSocket.java:112) ~[zookeeper-3.4.6.jar:3.4.6-1569965]
"This is a server-side setting"
This statement is incorrect, jute.maxbuffer is evaluated on client as well by Record implementing classes that receive InputArchive. Each time a field is read and stored into an InputArchive the value is checked against jute.maxbuffer. Eg ClientCnxnSocket.readConnectResult
I investigated it in ZK 3.4
There is no chunking in the response.
This is a server-side setting. You will get this error if the entirety of the response is greater than the jute.maxbuffer setting. This response limit includes the list of children of znodes as well so even if subs does not have a lot of data but has enough children such that their length of their paths exceeds the max buffer size you will get the error.
