Node fails on restart

[sebastiaoamaro]

Hi, we are a group of researchers analyzing the bugs found by Jepsen. During this process, we found a bug not reported in the version 2d1cf30.
This bug occurs when a node crashes on line:

redisraft/snapshot.c

Line 422 in 2d1cf30

int fd = open(rr->config->rdb_filename, O_CREAT|O_TRUNC|O_RDWR, 0666);

The following message appears when the node attempts to restart:

101:M 30 Apr 2025 10:57:46.065 # Short read or OOM loading DB. Unrecoverable error, aborting now.
101:M 30 Apr 2025 10:57:46.065 # Internal error in RDB reading offset 0, function at rdb.c:2284 -> Unexpected EOF reading RDB file
[offset 0] Checking RDB file raft1.rdb
--- RDB ERROR DETECTED ---
[offset 0] Unexpected EOF reading RDB file
[additional info] While doing: start
[additional info] Reading type 0 (string)
[info] 0 keys read

We did not yet test this on the main repository, when we do we will let you know.
