Accept Failure - Too many open files - IOException

I am getting this warning in logs.

2023-05-16 06:33:23  WARN: An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception. - Too many open files - IOException (...)

we have setup connection setting as per recommended on traccar site https://www.traccar.org/optimization but still getting this.

I wonder how many devices you have online.

I have around 1000 devices online.

You did disable all protocol ports that are not used.

Have you checked the process limit and how many connection you have?

I have checked process limit.

SyslogIdentifier=traccar
SuccessExitStatus=143
#WatchdogSec=600
Restart=on-failure
RestartSec=10
LimitNOFILE=50000
[Install]
WantedBy=multi-user.target

I have around total 1000 devices out of them 900 would be on gt06 port and currently open connections are 11424 on gt06 port.

How did you check the actual process limit?

And also why do you have so many connections? Have you configured the connection timeout?

Hi Anton,

I have checked this limit
LimitNOFILE=50000

Please let me know how to check process limit also.I have checked my traccar.config I have not set any timeout.how much timeout I should set ideally pls suggest.

It sounds like you haven't really read the documentation:

Hi Anton,
