KDC segmentation fault on krb5kdc

[Abhilash S]

Hello,

We are seeing crash in KDC process regularly.

KDC version : 1.9.2
we are running krb5 in thread option (krb5kdc -w 4)

some times child process hangs with out a clean shutdown and we need to
manually kill the hanging process

Error message from KDC:

rb5kdc[18170](Error): worker 18176 exited with status 11
krb5kdc[18172](info): shutdown signal received
krb5kdc[18172](info): closing down fd 8

>From Syslog we saw segmentation fault on krb5kdc
 kernel: krb5kdc[18176]: segfault at 0 ip 0000000000407781 sp
00007fff250d0ca0 error 4 in krb5kdc[400000+1b000]

Is there any issue in running KDC in multithread model ?
