| |
Hi,
I'd like to report following suspicious behaviour of 3.0.27 kernel.
On one of our production boxes, after upgrading from 3.0.26 to 3.0.27, applications started to behave weird after ~1 day uptime. Squid started reporting problems binding to port, nagios misbehaved, etc. I was forced to revert to 3.0.26. We tried to reproduce the problem but were unsuccessful. After ~1 week without problems with 3.0.26, I tried upgrading this production box to 3.0.27 again to see what happens and the problem appeared again after about one day.
imap started reporting problems: EMAIL DELIVERY CRITICAL - imap failed: IMAP RECEIVE CRITICAL - Could not connect to A.B.C.D port 993: IO::Socket::INET6 configuration
same for squid: commBind: Cannot bind socket FD 21 to 0.0.0.0: (98) Address already in use
nagios processes went totally nuts.
There was no other change except for the kernel upgrade. The box is x86_64 quad CPU 4GB machine, what might be important, we're using IPv6 as well. I don't see any suspicious (at least to me) patch between 3.0.26 and 3.0.27. Since it seems to take quite a long to reproduce, I haven't tried bisect yet, first wanted to ask - hasn't anyone experienced similar problems?
thanks a lot in advance!
with best regards
nik
