org.asynchttpclient.netty.request.NettyRequestSender - Too many connections: 100

Hello,

I think we need to adjust a connection limit for the tiny editor. But I can not find any documentation on this. Any ideas ?

Hi Jan,

I'd like to get some additional context to this message -
- Do you know what steps are needed to reproduce the problem?
- What does the end user see when the SystemOut.log has this issue, and which server is your log snippet from?
- Is everyone impacted when this happens?
- How often does this occur?
- When did this start happening?
- Does any specific activity lead to this problem?
- Does the problem resolve itself?

If we can't resolve this via the forum, we can collaborate with Tiny via an HCL Support case.

Thank you,
Michael Montani

Hello Michael,

I just want to know which component exactly is printing this message & how to configure the limit - I just can not find this in the documentation.
Since "com.ephox.spelling.data.Spelling" is listed I assume this error message is printed by an ephox-service, I assume the spelling service.
User impact & occurence does not matter here. I just need an answer to my question.


Thanks in advance !
Regards,
Jan

Hello,

HCL support provided the answer: \opt\ephox\application.conf parameter "max-connections" for "http" needs to be modified:

http {
max-connections = 300
}
