Replica (v 9.3.2) crashed with "PANIC: WAL contains references to invalid pages"

Hello everybody,

This weeked both replicas of our main db crashed at the same time with this error :

2014-02-09 11:42:51 GMT 0 52c671da.14da - PANIC: WAL contains references to invalid pages
2014-02-09 11:42:51 GMT 0 52c671da.14da - CONTEXT: xlog redo vacuum: rel 1663/16433/29449; blk 181466, lastBlockVacuumed 181463
2014-02-09 11:42:52 GMT 0 52c671d9.14d1 - LOG: startup process (PID 5338) was terminated by signal 6: Aborted
2014-02-09 11:42:52 GMT 0 52c671d9.14d1 - LOG: terminating any other active server processes

All three servers (main + two replicas) are on v. 9.3.2 running on Centos 6.4

We upgraded one month ago the main db from v 9.2.6 to 9.3.2 through pg_upgrade and had the replicas rebuilt on 9.3.2

I searched the mailing lists and found someone that had the same problem in the past but it seems that their problem was fixed by already released patches.

( see thread http://www.postgresql.org/message-id/675b7cee-b7f0-4e32-8e34-1efaf3ca5fe9@email.android.com)

So it seems that our problem is a new one since we are running the latest version.......

Thank you for your help
