[Koha] Error in SIP2's encoding when clients connect parallel in same time

[Ahmet Melih Başbuğ]

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.

(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
