mydns failing daily
 
Hello everyone,
I've got ispconfig 3.0.1.1 ubuntu 9.04-server x64 with kernel Linux 2.6.28-13.

My issue is every day mydns stops working. it maybe 1 to 3 times a day. I've checked with ps aux and the processes (its there twice) are both still running. a restart of mydns seems to take care of it. I've modified the mydns logging and provided the log entries below. If anyone has ANY ideas that would be awesome.. Thanks!!


Code:
mydns[319]: mydns: <IP> SOA <DOMAIN>.com. (687) NEED_ANSWER, High Priority IO Driven Task: FORMERR in query - NOTIFY is currently not a supported opcode
mydns[319]: mydns: read_tcp_length: no data for fd 8: ::1: Client closed TCP connection
mydns[319]: last message repeated 2 times
mydns[319]: mydns: Normal shutdown
mydns[319]: mydns: <HOSTNAME>.com up 10h25m58s (37558s) 1159 questions (0/s) NOERROR=1144 SERVFAIL=0 NXDOMAIN=1 NOTIMP=6 REFUSED=0 (11% TCP, 128 queries)

As this is a very specific problem and I'em not able to reproduce that on my systems, it might be the best if you contact the mydns developesr, maybe they know the resaon why their application fails:
