Hi, I am testing GnuGK in proxy mode and can only connect to 123calls.
If try to connect beyond 123calls, the following log appeared.

I seemed to have problems with memory allocation, so I confirmed ulimits.
------------
[root@localhost 1839]# cat limits
Limit Soft Limit Hard Limit Units
Max cpu time unlimited unlimited seconds
Max file size unlimited unlimited bytes
Max data size unlimited unlimited bytes
Max stack size 8388608 unlimited bytes
Max core file size 0 unlimited bytes
Max resident set unlimited unlimited bytes

------------
Changed the setting of systemd as follows.
------------
[root@localhost ~]# grep "open files" /proc/`pidof gnugk`/limits
Max open files 20480 20480 files
------------
No problem until 123 calls but tried to connect 124 calls, got the following state.

The result was the same when "Max open file" was set to "1025".

Please advise if there is any problem in setting GnuGK or OS.
Or is there a limit on the number of connections in proxy mode?
Thank you in advance for your help.
Kind regards,
Yokoo
