Hi Matthew, sorry for the late answer, I was quite busy.
So it's not working neither with the network_default_read_size option you gave me, and I'm not using libevent. For the context, it's a SI (XEP-0096) file transfer, I'm sending the file (~400 Mio) and I'm forcing the use of the proxy for the test. My chunks have a size of 2**16 (64 Kio) when disconnection occurs. If I set a size of 4096, there is no problem. I'm sending the file, so Gajim is actually not in cause here. If I do a direct connection I have no problem neither. Here is the significant part of the logs: --- logs socket debug server.lua: accepted new client connection from 127.0.0.1:42662 to 5000 mod_proxy65 debug SOCKS5 greeting complete mod_proxy65 debug SOCKS5 target connected for session e83c1d0c64441f3a22a5f74a27d4f7dd17a8c066 c2s1b3e530 debug Received[c2s]: <iq id='H_44' type='result' to='go...@necton3.int/SàT' from='lou...@necton3.int/Gajim'> necton3.int:log_events debug necton3.int firing event: pre- iq/full necton3.int:log_events debug necton3.int firing event: iq/full socket debug server.lua: accepted new client connection from 127.0.0.1:42664 to 5000 mod_proxy65 debug SOCKS5 greeting complete mod_proxy65 debug SOCKS5 initiator connected for session e83c1d0c64441f3a22a5f74a27d4f7dd17a8c066 c2s1c0bac0 debug Received[c2s]: <iq id='H_45' type='set' to='proxy.necton3.int'> necton3.int:log_events debug necton3.int firing event: pre- iq/host proxy.necton3.int:proxy65 debug Transfer activated (sid: 5620a228-2256-4004-9149-6ca8593a461b, initiator: go...@necton3.int/SàT, target: lou...@necton3.int/Gajim) mod_proxy65 debug ondisconnect: 'receive buffer exceeded' mod_proxy65 debug ondisconnect: 'false' socket debug server.lua: closed client handler and removed socket from list socket debug server.lua: closed client handler and removed socket from list --- end logs I have added myself the "ondisconnect" log, because else mod_proxy65 was not logging the err. The xml stream is not disconnected, it's the Socks5 client only which is disconnected. So I currently workaround this by setting a 4Kio limit for proxies, which is a reasonable value anyway.
