Standby and replication terminated due to Server PANIC

Hi all,

I have a Postgresql 9.2 instance running on a CentOS6.3 box.Yesterday i
setup a hot standby by using pgbasebackup. Today i got the below alert
from standby box :

[1] (from line 412,723)
2013-04-24 23:07:18 UTC [13445]: [6-1] user= db= host= PANIC:
_bt_restore_page: cannot add item to page

When i check, the replication is terminated due to slave DB shutdown. From
the logs i can see below messages :-

2013-04-24 23:17:16 UTC [26989]: [5360083-1] user= db= host= ERROR: could

I checked in global directory of master, the directory 14078 doesn't exist.

Anyone has faced below issue ?

Thanks
