Hi FreeIPA users,
I've been haunted across installs by a sporadic krb5kdc segfault, the
especially fun part is that it seems to bring the service down on all of
the servers at once! Restarting it brings everything back again quite
happily..
The last and only useful krb5kdc.log entry is:
Nov 29 12:12:13
ipa1.redacted.net krb5kdc[20700](Error): worker 20705
exited with status 139
and in terms of segfault related, dmesg:
[271761.231312] krb5kdc[20705]: segfault at fffffffffffffff8 ip
00007fe492d56b80 sp 00007ffc55c38c80 error 5 in ipadb.so[7fe492d4c000+19000]
I was hoping that moving from our Fedora based install to CentOS would make
this go away, but it seems to have followed us!
Any advice as to where best to seek more useful log data?
If you would install debuginfo packages for ipa / krb5, and enable abrt
processing, we might get a whole backtrace.
There were some fixes in ipadb.so recently in upstream.
