dovecot - Jun 2009 - record points outside file error with dovecot revision 9116:9ae55b68cf61

I use mbox with mbox-snarf plugin.

I get errors like:

  dovecot: IMAP(testuser): Corrupted index cache file /full/path/ 
dovecot.index.cache:  record points outside file

The errors can be in either folders or INBOX.

I put some syslog statements in src/lib-index/mail-cache-lookup.c to  
help understand this.

   if (offset + sizeof(*rec) > cache->mmap_length) {
                 mail_cache_set_corrupted(cache, "record points  
outside file");
                 syslog(LOG_DEBUG,"mail_cache_get_record rec->size is  
%d ", rec->size);
                 syslog(LOG_DEBUG,"cache->mmap_length is %d ",
cache-
 >mmap_length);
                 syslog(LOG_DEBUG,"offset is %d ", offset);
                 return -1;
}


syslog: mail_cache_get_record rec->size is 268595472
syslog: cache->mmap_length is 4096
syslog: offset is 1630760037



Oh I forgot to print off sizeof(*rec). Would that help?

Thanks,
Jonathan

So you're using AIX? Do you also happen to use NFS? Can you reproduce
this error by running imaptest for a while? http://imapwiki.org/ImapTest

No NFS here. The filesystem is called GPFS. It is a clustered FS. I'll 
work on reproducing with imaptest. Once I reproduce, I'll give more 
details about how I run dovecot.

thanks,
