Hello. We configure SIP2 for RFID in a system for KOHA. Configuration is allright, all clients can connect and get results from SIP. However after a time, encoding is broken and I have to restart SIP2 in command line. 9300CNtest1|COtest1|CP34| 941 1720060110 215612AO27|AB102700011725| 1803020120161122 085258AB102700011725|AJKütüphane Üzerine Bir Araştırma |AQ27|BG27| I open 2 terminal and connect in same time by telnel linux1$> telnet 192.168.2.1 6001 linux2$> telnet 192.168.2.1 6001 (i send these commands in same time) 9300CNtest1|COtest1|CP34| 941 1720060110 215612AO34|AB21312311| 1803020120161122 085258AB102700011725|AJK�t�phane �zerinde Ara?t?rma|AQ3|BG3| Then I restart SIP2 and it result correct in one terminal ; 9300CNtest1|COtest1|CP34| 941 1720060110 215612AO34|AB21312311| 1803020120161122 085258AB102700011725|AJKütüphane Üzerine Bir Araştırma |AQ3|BG3| (correct result however it broken after a time) What should i do when clients connect in paralellism? I divide ports but it doesn't work. One client - one port. This client connect at same time and all SIP2 in ports are broken. I write a crontab command which restart SIP2 configuration every 30 minutes. but problem continue Thanks Ahmet
